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
between 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.

Part 1
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
μ1 be the mean daily time spent on the website for male
college students and
μ2 be the mean daily time spent on the website for
female college students. Determine the hypotheses. Choose the
correct answer below.
A.
H0: μ1=μ2
H1: μ1≠μ2
B.
H0: μ1≤μ2
H1: μ1>μ2
C.
H0: μ1≠μ2
H1: μ1=μ2
D.
H0: μ1≥μ2
H1: μ1<μ2

Part 4
Choose the correct conclusion below.
A. Do not reject H0. There is insufficient evidence that
the means differ.
B. Reject H0. There is sufficient evidence that the
means differ.
C. Reject H0. There isinsufficient evidence that the
means differ.
D.Do not reject H0. There is sufficient evidence that
the means differ.
Part 5
b. In addition to equal​ variances, what other
assumption is necessary in​ (a)?
A. In addition to equal​ variances, it must be assumed
that the sample means are equal.
B. In addition to equal​ variances, no other assumptions
must be made because the sample sizes are large enough
​(
≥30 for each​ sample).
C. In addition to equal​ variances, it must be assumed
that the population sizes are equal.
D. In addition to equal​ variances, it must be assumed
that the samples are specifically chosen and not independently
sampled.
