The average American gets a haircut every 39 days. Is the average smaller 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.39, 41, 39, 31, 44, 36, 29, 42, 45, 32, 41, 33What can be concluded at the the a = 0.10 level of significance level of significance?a. For this study, we should use t-test for a population meanb. The null and alternative hypotheses would be:Ho: PU VSelect an answer Vc. The test statistic(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 ? vaf. Based on this, we should Select an answerg. Thus, the final conclusion is thatthe null hypothesis.O The data suggest the populaton mean is significantly lower than 39 at a = 0.10, so there issufficient evidence to conclude that the population mean number of days between haircuts forcollege students is lower than 39.O The data suggest the population mean number of days between haircuts for college students isnot significantly lower than 39 at a = 0.10, so there is insufficient evidence to conclude thatthe population mean number of days between haircuts for college students is lower than 39.O The data suggest the population mean is not significantly lower than 39 at a = 0.10, so thereis sufficient evidence to conclude that the population mean number of days between haircutsfor college students is equal to 39.
