Question
A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n= 187, x=7.81, s=1.98. Use a 0.05 significance level to test the claim that the population mean of such ratings is less than a00.
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 altemative hypotheses?
O A. Ho =8.00
H u+8.00
O B. H, p=8.00
H,p<8.00
O D. Ho u=8.00
H, p>8.00
OC. Ho u<8.00
H, p>8.00
Determine the test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
E(Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
V H. There is
V evidence fo conclude that the mean of the population of ratings is
V 8.00.
