A student at a four-year college claims that mean enrollment at four-year colleges is higher than at two- year colleges in the United States. Two surveys are conducted. Of the 35 four-year colleges surveyed, the mean enrollment was 5,466 with a standard deviation of 8,191. Of the 35 two-year colleges surveyed, the mean enrollment was 5,068 with a standard deviation of 4,777. Test the student's claim at the 0.10 significance level. a) The null and alternative hypothesis would be: Ho: PF = PT PT H₁: PF t = Ho:μF = HT H₁:μF > HT Ho: PF = PT H₁: PF PT p= Ho:μF = HT H₁: PF PT Ho: PF = PT H₁: PF PT b) Determine the test statistic. Round to two decimals. Ho: PF = HT H1:μF

Question
A student at a four-year college claims that mean
enrollment at four-year colleges is higher than at two-
year colleges in the United States. Two surveys are
conducted. Of the 35 four-year colleges surveyed, the
mean enrollment was 5,466 with a standard deviation
of 8,191. Of the 35 two-year colleges surveyed, the
mean enrollment was 5,068 with a standard deviation
of 4,777. Test the student's claim at the 0.10
significance level.
a) The null and alternative hypothesis would be:
Ho: PF = PT
H1: PF PT
t =
Ho: μF = HT
Hy: MF > με
Ho: PF = PT
H₁: PF > PT
P =
O Ho: HF = HT
H₁:μF T
O Ho: PF = PT
H₁: PF PT
b) Determine the test statistic. Round to two decimals.
OH:#F = UT
H: μF < με
c) Find the p-value and round to 4 decimals.
d) Make a decision.
O Reject the null hypothesis
O Fail to reject the null hypothesis
e) Write the conclusion.
There is sufficient evidence to support the claim
that enrollement is high at a four-year college
than a two-year college.
There is not sufficient evidence to support the
claim that enrollement is high at a four-year
college than a two-year college.
