A data set includes data from student evaluations of courses.
The summary statistics are
n=85​,
x=4.09​,
s=0.55.
Use a
0.05
significance level to test the claim that the population of
student course evaluations has a mean equal to
4.25.
Assume that a simple random sample has been selected. Identify
the null and alternative​ hypotheses, test​ statistic,
P-value, and state the final conclusion that addresses the original
claim.
Question content area bottom
Part 1
What are the null and alternative​ hypotheses?
A.
H0​:
μ=4.25
H1​:
μ≠4.25
Your answer is correct.
B.
H0​:
μ=4.25
H1​:
μ<4.25
C.
H0​:
μ≠4.25
H1​:
μ=4.25
D.
H0​:
μ=4.25
H1​:
μ>4.25
Part 2
Determine the test statistic.
