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:μF = PT PT H₁:μF O Ho: PF = PT H₁: PF PT Ho: PF = HT H₁:P HT Ho: PF = PT H₁: PF > PT b) Determine the test statistic. Round to two decimals. t = c) Find the p-value and round to 4 decimals. p= d) Make a decision.

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:
O Ho:μF = PT
H₁: HP HT
O Ho: PF = PT
H₁: PF PT
Ho: PF
= HT
H₁:μp <HT
Ho: PF = PT
H₁: PF PT
HT
Ho:μF
H: με > μη
Ho: PF = PT
H₁: PF > PT
b) Determine the test statistic. Round to two decimals.
t =
c) Find the p-value and round to 4 decimals.
p=
d) Make a decision.
O Reject the null hypothesis
Fail to reject the null hypothesis
e) Write the conclusion.
O 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.
