hypothesis. The alternative hypothesis is Ha:μ 3200 Step 3: Test Statistic: z= Following the provided information, the Significance Level is α=0.05. The alternative hypothesis is Ha: μ>3200; therefore, the given test is a one-tailed (upper-tailed) z-test. Step 4: Critical Value and Rejection Region: The critical value for significance level α=0.05 for an upper-tailed z-test is given as 1.645. Rejection Region: Reject H_0,if z-statistic>1.645. Step 5: Assumptions: The sample size in this speculation

Doing this can better your chance of success in todays sports(Porreca). The use of analyzing statistics in sports is a fairly new concept, however statistics in sports have been kept for a little over 50 years.

5 Applied Statistics Introduction Today’s consumers are constantly trying to judge the quality of products. But what is quality? How and by whom is quality determined? Some would say the designer creates specifications, which in turn dictate the quality of a product. That quality is also based on the acceptable value of a part within a whole product. Statistics are commonly used in manufacturing processes to control and maintain quality. This activity will allow you to apply statistics in order to

Statistics, like physic, math, or any other discipline, is a large and diverse field. The method of statistical analysis is to analyze the fact in a research study and to bring forth a concrete result with many contents. The content analysis of statistical research may provide many useful results where it informs the readers of a current problem or a situation that may exist within a population, an organization, or in a community. There are many types of data that can be identified in the topics

In order to receive full credit on calculated answers, please show your work. (Use Word's equation editors, etc., and/or provide a short written description as to how you obtained the final result.) Exercise 11 (4 points per question) 1. What demographic

The measure results of the data sets are not surprising. The means of each of the independent variables reflect the arbitrary evaluations of each of these parameters. All the variables have relatively small standard errors compare to their mean. Also, the medians and the means mostly lie fairly close to each other, in another word, the means well indicate the actual distribution of the data sets. One of the possible concerns is that per capita disposable income has both high standard deviation and
