The average American gets a haircut every 34 days. Is the average different for college students? The data below shows the results of a survey of 16 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 40, 41, 34, 36, 30, 43, 44, 28, 42, 47, 27, 44, 37, 36, 38, 36 What can be concluded at the the a = 0.01 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: Select an answer H1: Select an answer c. The test statistic ( ? V (please show your answer to 3 decimal places.) d. The p-value (Please show your answer to 3 decimal places.) e. The p-value is (? v a f. Based on this, we should | Select an answer the null hypothesis. g. Thus, the final conclusion is that ... | The data suggest the populaton mean is significantly different from 34 at a = 0.01, so there is sufficient evidence to conclude that the population mean number of days between haircuts for college students is different from 34. The data suggest the population mean is not significantly different from 34 at a = 0.01, so there is sufficient evidence to conclude that the population mean number of days between haircuts for college students is equal to 34. The data suggest the population mean number of days between haircuts for college students is not significantly different from 34 at a = 0.01, so there is insufficient evidence to conclude that the population mean number of days between haircuts for college students is different from 34.
