![### Hypothesis Testing: Compulsive Buyers Questionnaire Score
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. 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.
