Chillax USA Today reported results from a Research Now for Keurig survey in which 1458 men and 1543 women were asked ibis: “In a typical week, how often can you kick back and relax?”
a. Among the women, 19% responded with “rarely, if ever.” What is the exact value that is 19% of the number of women surveyed?
b. Could the result from part (a) be the actual number of women who responded with “rarely, if ever”? Why or why not?
c. What is the actual number of women who responded with “rarely, if ever”?
d. Among the men who responded, 219 responded with “rarely, if ever.” What is the percentage of men who responded with “rarely, if ever.”?
e. Consider the question that the subjects were asked. Is that question clear and unambiguous so that all respondents will interpret the question the same way? How might the survey be improved?

The researcher conducts a study among 93 newly diagnosed arthritis patients and finds the mean trough to be 4.1 micrograms/mL with a standard deviation of 2.4 micrograms/mL. The researcher wants to test at the 5% level of significance if the trough is different than previously reported or not. Z statistics will be used. Complete Step 5 of hypothesis testing: Conclusion. State whether or not you would reject the null hypothesis and why.
