The average American gets a haircut every 38 days. Is the average larger for college students? The databelow shows the results of a survey of 12 college students asking them how many days elapse betweenhaircuts. Assume that the distribution of the population is normal.41, 36, 37, 39, 33, 46, 42, 35, 40, 46, 31, 40What can be concluded at the the a = 0.05 level of significance level of significance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Ho: ?Select an answerH1: ? V Select an answerc. The test statistic ? V(please show your answer to 3 decimal places.)|(Please show your answer to 3 decimal places.)d. The p-value =e. The p-value is ? Vaf. Based on this, we should Select an answerg. Thus, the final conclusion is that ...the null hypothesis.O The data suggest the population mean number of days between haircuts for college students isnot significantly higher than 38 at a = 0.05, so there is insufficient evidence to conclude thatthe population mean number of days between haircuts for college students is higher than 38.The data suggest the population mean is not significantly higher than 38 at a = 0.05, so thereis sufficient evidence to conclude that the population mean number of days between haircutsfor college students is equal to 38.OThe data suggest the populaton mean is significantly higher than 38 at a = 0.05, so there issufficient evidence to conclude that the population mean number of days between haircuts forcollege students is higher than 38.
