The average American gets a haircut every 40 days. Is the average smaller for college students? The data below shows the results of a survey of 12 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 46, 40, 32, 37, 41, 40, 39, 41, 39, 31, 46, 44 What can be concluded at the the a = 0.05 level of significance level of significance? B q q 8 8 a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: v H₁: [ c. The test statistic tv d. The p-value = 0.594 e.
