A random sample of 43 subjects who identified themselves as compulsive buyers was obtained and given a questionnaire. They had a mean questionnaire score of 0.56 with a standard deviation of 0.19. Test the claim that the population of self-identified compulsive buyers has a mean greater than the mean of 0.56 for the general population. Use a 0.05 significance level. C State the null and alternative hypotheses. O A. Ho: μ=0.56 OB. Ho: μ = 0.56 Hg:μ <0.56 H₂: μ> 0.56 O C. Ho: μ*0.56 O D. Ho: μ = 0.56 Ha: μ0.56 H₂:μ=0.56 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 sufficient evidence to support the claim that the population of self-identified compulsive buyers has a mean greater than the mean of 0.56 for the general population. O B. The P-value is greater than the significance level. There is sufficient evidence to support the claim that the population of self-identified compulsive buyers
