100%
A random sample of 41 subjects who identified themselves as compulsive buyers was obtained and given a questionnaire. They had a mean questionnaire score of
0.55 with a standard deviation of 0.13. Test the claim that the population of self-identified compulsive buyers has mean greater than the mean of 0.53 for the
general population. Use a 0.05 significance level.
O
State the null and alternative hypotheses.
OA. Ho: 0.53
OB. Ho: μ=0.53
H₂: μ = 0.53
Hg:μ <0.53
OC. Ho: μ = 0.53
O D. Ho: μ=0.53
H₂:μ>0.53
H₂: μ*0.53
Find the z-score.
Z= (Round to two decimal places as needed.)
Find the P-value.
The P-value is
(Round to four decimal places as needed.)
State the conclusion.
O A. The P-value is less than or equal to the significance level. There is not sufficient evidence to support the claim that the population of self-identified
compulsive buyers has mean greater than the mean of 0.53 for the general population.
OB. The P-value is less than or equal to the significance level. There is sufficient evidence to support the claim that the population of self-identified
