Question
A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 191, x=6.52, s= 1.85. 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?
ОВ. Но: н37.00
H1:µ> 7.00
Ο Α. Ho . μ= 7.00
H1: µ#7.00
O c. Ho:μ< 7.00
O D. Ho: u= 7.00
H1: µ>7.00
H: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.
V Ho. There is
V evidence to conclude that the mean of the population of ratings is
7.00.
