Use a = 0.1 to test the claim that the age distribution of the general Canadianpopulation fits the age distribution of the residents of Red Lake Village. Given that0.25 < P-Value < 0.50, will you reject or fail to reject the null hypothesis that thepopulation fits the specified distribution of categories?O Since the P-Value is greater than a, we fail to reject the null hypothesis thatthe population fits the specified distribution of categories. At 0.1 level ofsignificance, we conclude that the population fits the specified distribution ofcategories.O Since the P-Value is greater than a, we fail to reject the null hypothesisthat the population fits the specified distribution of categories.

O CONFIDENCE INTERVALS AND HYPOTHESIS TESTING Choosing an appropriate sample size Day Jears Many college graduates who are employed full-time have longer than 40-hour work weeks. Suppose that we wish to estimate the mean number of hours, u, worked per week by college graduates employed full-time. We'll choose a random sample of college graduates employed full-time and use the mean of this sample to estimate u. Assuming that the standard deviation of the number of hours worked by college graduates is 6.10 hours per week, what is the minimum sample size needed in order for us to be 90% confident that our estimate is within 1.3 hours per week of u? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).
