The mean age of principals in a local school district is 56.7 years. If a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis? Select one: a. There is sufficient evidence to support the claim ? = 56.7. b. There is not sufficient evidence to reject the claim ? = 56.7. c. There is sufficient evidence to reject the claim ? = 56.7. d. There is not sufficient evidence to support the claim ? = 56.7.

The mean age of principals in a local school district is 48.6 years. The following hypothesis test is performed: . The p-value for the hypothesis test is p-value = 0.04. How should you interpret this hypothesis test? Group of answer choices Do not reject Ho - There is not sufficient evidence to reject the claim ÎĽ = 48.6 Accept Ho - There is not sufficient evidence to support the claim ÎĽ = 48.6. Do not reject Ho -There is sufficient evidence to support the claim ÎĽ = 48.6. Reject Ho - There is sufficient evidence to reject the claim ÎĽ = 48.6.

The mean age of principals in a local school district is 50.2 years. If a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis? There is sufficient evidence to support the claim ÎĽ = 50.2. There is not sufficient evidence to reject the claim ÎĽ = 50.2. There is sufficient evidence to reject the claim ÎĽ = 50.2. There is not sufficient evidence to support the claim ÎĽ = 50.2.
