...Describe the role of statistics in business decision making. Provide at least three examples or problem situations in which statistics was used or could be used. Statistics plays a significant part in successful business decisions. Any successful entrepreneur has to be especially sharp and correct when making business decisions. The entrepreneur should have a feeling for the market demand for the company's products and should therefore be able to identify what to produce products or services that will sell. The volume of sales may also be accurately estimated. Statistics will help entrepreneurs to align production according to the market demand. Utilizing business statistics the quality of the products may also be verified in a more scientific manner to save on measuring cost. http://voices.yahoo.com/importance-statistics-business-decisions-7356560.html A major metropolitan newspaper randomly sampled 150 readers from their list of 100,000 subscribers. They asked whether the paper should increase its coverage of local news. Forty percent of the sample wanted more local news. What is the 95% confidence interval for the proportion of readers who would like more coverage of local news? (A) 0.32 to 0.48 (B) 0.33 to 0.47 (C) 0.34 to 0.46 (D) 0.35 to 0.45 (E) 0.36 to 0.44 Solution The correct answer is (A).

...Exercise: 11 1. What demographic variables were measured at least at the interval level of measurements? Number of hours working per week and Length of labor 2. What statistics were used to describe the length of labor in this study? Were these appropriate? Descriptive Yes, Frequency (30) and mean (14.63) are used to describe the data. 3. What other statistic could have been used to describe the length of labor? Provide a rationale for your answer. Length of labor was described for both the experimental and control groups using means (14.63) and standard deviations (7.78). The exact length of labor was obtained, providing ratio level data that are descriptively analyzed with means and standard deviations. 4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide a rationale for your answer. No, the distributions of scores were not similar for the two groups. Experimental group has slightly higher dispersion (n=30 and SD= 7.78) than control group (N=33 and SD=7.2). Standard deviation decreases with larger sample sizes. 5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer. Yes. Bottle-feeding was the mode for the experimental (53.1%) and the control (50%) groups since it was the most frequent type of feeding used by both groups 6. What was the marital status mode for the subjects in the experimental and control groups? Provide both the......

... MA3110 Statistics Dr. P. A. Williams What is my meaning of Statistics? My meaning or definition of statistics is that of its base word itself. Stat. Along with other elements that would make it a definition or an opinion of sort, but I’m sure that I won’t be far from what others may say it means or what they think it means. Stat is defined as with no delay; at once. When most of us think about statistics, we think of comparisons, of two or more entities but ones balance might be more or less as well as winning and losing. There is still that scale that separates the two where one is ahead of the other. The people analyzing and drawing conclusions are getting this information have to get it out to those that follow up on whatever the subject may be fast because people want to know. It’s said that Statistics is the science of planning studies and experiments, obtaining data, and then organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data according to (Pearson’s Elementary Statistics Using Microsoft Excel by, Mario F. Triola). This is the same as I said without including all of the other tools needed, or used in Statistics. Television shows are another example being on statistic radar so to speak.

...Statistics is a powerful resource to determine important information. Statistics is used to determine whether the outcome of an experiment is the result of a relationship between specific factors or merely the result of chance. This concept is commonly used in the medical field to test drugs and vaccines and to determine causal factors of disease. Statistical also is used in the fields of psychology, environmental biology and other disciplines in which research is conducted through experimentation. Statistics are the mathematical calculations of numeric sets or populations that are manipulated to produce a probability of the occurrence of an event(Sullivan, 2003). A sample is used, and the results of the calculation are applied to an entire population. For example, it might be said that 80 percent of all adults in the United States drive a car. It would be difficult to ask each adult in the U.S. whether he or she drives a car, so a random number of people could be questioned, and the data could be statistically analyzed and generalized to apply to all adults in the U.S. This paper it shows three examples on how statistics relates to current life. Using the knowledge that I have obtained from this course, I will demonstrate techniques we have discussed in class to answer these questions. In 1798, Henry Cavendish measured the density of the earth using an instrument called a torsion balance. While the density is obviously not uniform, the value of the mean density is......

...The article I chose suggests that Roman Catholics in the United States hope that the next pope could be younger and lead the church in a more liberal way regarding issues, such as birth control and same-sex marriage. The statistics is based on the latest New York Times/CBS News telephone poll conducted on landlines and cellphones from February 23 to 27 with 1,585 adults nationwide. Three-fourths of interviewers thought Pope Benedict should step down because he did a bad job dealing with sexual abuse. The poll suggested that many American Catholics are not confident about the church’s hierarchy since the bishops and cardinals do not understand their needs. The sample of telephone poll was randomly selected to ensure that each region of the country has almost same share of all telephone numbers, so it seems justified geographically. However, there is uncertainty in the survey because the margin of sampling error is plus or minus 4% for the 580 Catholics. An effective way to reduce the margin of error is to increase the sample size. There is also nonresponse error in the survey because some people do not answer calls from strangers, or refuse to answer the poll. In addition, due to selection bias, the opinions of those who agreed to be interviewed only reflect a certain part of the population. The article did well in analyzing from a series of data, mainly on the percentage of sample size. For example, the poll showed that 40 percent thought the pope is......

Revised Data. Test for Normal Distribution To proceed with the analysis it is necessary to determine if the data are distributed normally. The Histogram below as well as the Descriptive Statistics (Appendix 1, Table 1b) show that the data distribution is leptokurtic (kurtosis is 2,021) and negatively skewed (skewness -,240). We can determine several outliers (Appendix 1, Table 1c, Table 1d) with extreme ratios. In cases #46 and #178 JSL is more than the highest option provided in the questionnaire. That could be a mistake in data entering or the respondent wanted to emphasise his/her satisfaction level. These cases were delisted.

...Descriptive and Inferential Statistics ________________________________________ Statistics can be broken into two basic types. The first is known as descriptive statistics. This is a set of methods to describe data that we have collected. Ex. Of 350 randomly selected people in the town of Luserna, Italy, 280 people had the last name Nicolussi. An example of descriptive statistics is the following statement : "80% of these people have the last name Nicolussi." Ex. On the last 3 Sundays, Henry D. Carsalesman sold 2, 1, and 0 new cars respectively. An example of descriptive statistics is the following statement : "Henry averaged 1 new car sold for the last 3 Sundays." These are both descriptive statements because they can actually be verified from the information provided. The second type of statistics in inferential statistics. This is a set of methods used to make a generalization, estimate, prediction or decision. Ex. Of 350 randomly selected people in the town of Luserna, Italy, 280 people had the last name Nicolussi. An example of inferential statistics is the following statement : "80% of all people living in Italy have the last name Nicolussi." We have no information about all people living in Italy, just about the 350 living in Luserna. We have taken that information and generalized it to talk about all people living in Italy. The easiest way to tell that this statement is not descriptive is by trying to verify it based upon the information provided. Ex....
