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 a mean greater than the mean of 0.53 for the general population. Use a 0.05 significance level. State the null and alternative hypotheses. O A. Ho: 0.53 O B. Ho: μ=0.53 Ha: μ = 0.53 Hg:μ <0.53 OC. Ho: μ=0.53 Ha: μ*0.53 O D. Ho: H=0.53 H₂:μ>0.53 Find the z-score. Find the P-value. The P-value is (Round to four decimal places as needed.) (Round to two decimal places as needed.)

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
