A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are
n=197,
x=6.54,
s=2.01.
Use a
0.05
significance level to test the claim that the population mean of such ratings is less than
7.00.
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.
What are the null and alternative hypotheses?
A.
H0:
μ=7.00
H1:
μ>7.00
B.
H0:
μ<7.00
H1:
μ>7.00
C.
H0:
μ=7.00
H1:
μ≠7.00
D.
H0:
μ=7.00
H1:
μ<7.00
Determine the test statistic.

(Round to two decimal places as needed.)
Determine the P-value.

(Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
