A local college newsletter reported that the average American college student spends one hour (60 minutes) on a social media website daily. But you wonder if there is a difference betveen males and females. Attached below is a sample of 60 users of the website (30 males and 30 females) and their recorded daily time spent on the website. Complete (a) and (b) below. E Click the icon to view the sample times. a. Assuming that the variances in the population of times spent on the website per day are equal, is there evidence of a difference in the mean time spent on the website per day between males and females? (Use a 0.05 level of significance.) Let u, be the mean daily time spent on the website for male college students and u, be the mean daily time spent on the website for female college students. Determine the hypotheses. Choose the correct answer below. O A. Ho: H1 SH2 H,: > H2 OC. Ho: H 2 42 H: H1 <H2 O B. Ho: H1 H2 H,: H =42 D. Hg: H1 = H2 Determine the test statistic. tSTAT = 2.52 (Round to two decimal places as needed.) i Sample times Find the p-value. p-value = 0.019 (Round to three decimal places as needed) Daily time spent (in minutes) on the website for 30 males Choose the correct conclusion below. 5 720 270 45 180 960 45 30 10 45 120 60 210 210 210 240 240 180 45 120 270 35 60 180 60 15 45 15 120 100 A.

In addition to equal variances, no other assumptions must be made because the sample sizes are large enough (2 30 for each sample). B. In addition to equal variances, it must be assumed that the samples are specifically chosen and not independently sampled. C. In addition to equal variances, it must be assumed that the sample means are equal. D. In addition to equal variances, it must be assumed that the population sizes are equal.
