### Hypothesis Testing: Compulsive Buyers Questionnaire ScoreA 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. We will conduct a hypothesis test to determine if the population of self-identified compulsive buyers has a mean greater than the mean of 0.56 for the general population. The significance level for the test is 0.05.---#### State the null and alternative hypotheses.Choose the correct set of hypotheses:**A.**- $ H_0 $: $ \mu = 0.56 $- $ H_a $: $ \mu > 0.56 $**B.**- $ H_0 $: $ \mu = 0.56 $- $ H_a $: $ \mu < 0.56 $**C.**- $ H_0 $: $ \mu \neq 0.56 $- $ H_a $: $ \mu = 0.56 $**D.**- $ H_0 $: $ \mu = 0.56 $- $ H_a $: $ \mu \neq 0.56 $---#### Find the z-score.Calculate the z-score and round to two decimal places:\[ z = \_\_\_\_ \]---#### Find the P-value.Determine the P-value and round to four decimal places:\[ \text{The P-value is } \_\_\_\_ \]---#### State the conclusion.Based on the P-value, choose the correct conclusion:**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.**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 has a mean greater than the mean of 0.56 for the general population.---This example guides you through conducting a hypothesis test for a mean, interpreting results, and making conclusions based on statistical evidence.
