A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n= 191, x= 6.58, s = 1.96. Use a 0.01 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? O A. Ho: H=7.00 O B. Ho: H =7.00 H,:H>7.00 H1:µ<7.00 OC. Ho:H<7.00 O D. Ho: μ= 7.00 H:H#7.00 H:µ>7.00 Determine the test statistic. (Round to two decimal places as needed.)

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= 6.58, s = 1.96. Use
a 0.01 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?
Ο Α. H μ=7.00
O B. Ho: µ= 7.00
H4: µ>7.00
H1:µ<7.00
OC. Ho: H<7.00
O D. Ho: u = 7.00
H1: µ>7.00
H1:H#7.00
Determine the test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
|(Round to three decimal places as needed.)
ate 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
V 7.00.
