A simple random sample of shoppers was collected in a large departmental store to study some certain consumer behaviours. Among the questions asked was, "do you enjoy shopping for clothing?" and "are you Male or Female?" Here are partial summarized data for this question: Do you enjoy shopping? Yes No Not relevant I buy what I have to Females 34 68 Total 99 174 31 126 If the null hypothesis is: Ho :Gender and enjoying shopping are independent. Use alpha = 0.05, then do the following: (Use two decimal places when appropriate) (a) Find the expected number of people with who said they like to shop and are Female: (b) Find the expected number of people who said they don't like to shop and are Female: (c) Find the expected number of people who responded with a Not relevant I buy what I have to and who are not Female: (d) Find the test statistic: (Use two decimal places when appropriate) (e) Find the degrees of freedom: () Find the critical value: (Use two decimal places when appropriate) (9) The final conclusion is O A. There is not sufficient evidence to reject the null hypothesis. B. We can reject the null hypothesis that gender and enjoying shopping are independent.

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?

Suppose we are interested in the relationship between individuals’ place of residence (rural versus urban) and their political affiliation (Republican versus Democrat). A random sample of 100 individuals yields the following crosstabulation: Political Affiliation Place of Residence Republican Democrat Rural 21 29 Urban 14 36 a) In words, what is the null hypothesis to be tested? b) Is the relationship between place of residence and political affiliation statistically significant at the .05 level? (Be sure to show the statistics that lead to your decision.) c) Compute and interpret an appropriate measure of association for the relationship between these two variables.
Forbes reports that women in general trust recommendations from Pinterest more than recommendations from any other social network platform. But does trust in Pinterest differ by gender? The following sample data show the number of women and men who state in a recent survey that they trust recommendations made on Pinterest.
