SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.Use the traditional method to test the given hypothesis. Assume that the samples are independent and that they havebeen randomly selected45) A researcher finds that of 1,000 people who said that they attend a religious service at least 45)once a week, 31 stopped to help a person with car trouble. Of 1,200 people interviewedwho had not attended a religious service at least once a month, 22 stopped to help a personwith car trouble. At the 0.05 significance level, test the claim that the two proportions areequal.

Members of fraternities and sororities are required to volunteer for community service. Do fraternity brothers work fewer volunteer hours on average than sorority sisters? The data below show the number of volunteer hours worked for thirteen randomly selected fraternity brothers and eleven randomly selected sorority sisters. Brothers: 14 7 11 13 9. 11 8 12 7 13 10 13 Sisters: 13 19 16 11 11 19 5 10 16 17 7 | d. The p-value is ? O a e. Based on this, we should Select an answer the null hypothesis. f. Thus, the final conclusion is that ... The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population mean volunteer hours for fraternity brothers is less than the population mean volunteer work hours for sorority sisters.
