What is "Statistics"? Give two types of statistics.

One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. After taking the test and seeing your score for this subsection, you're interested in the mean score,  μ , among the general population on this subsection. The website reports that  μ  is  148 , but you believe that  μ  is greater than  148 . You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection is  152  and that the standard deviation of their scores is  28 . Based on this information, answer the questions below. What are the null hypothesis ( H0 ) and the alternative hypothesis ( H1 ) that should be used for the test? H0 :  μ  is   H1 :  μ  is  In the context of this test, what is a Type I error?A Type I error is  the hypothesis that  μ  is   when, in fact,  μ  is  .Suppose that you decide not to…

Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants. He then measures whether they choose to sit next to other participants or if they sit far away on their own. What is the best test to run for this study and why?

Traditional statistics (means, variances, and hypothesis tests) are not used to evaluate the results from a single-case study. Explain how the results are evaluated.
