Question

the mean age of bus drivers in chicago is 49.7 years. if a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis?
a. there is not sufficient evidence to support the claim \\( \mu = 49.7 \\).
b. there is sufficient evidence to support the claim \\( \mu = 49.7 \\).
c. there is sufficient evidence to reject the claim \\( \mu = 49.7 \\).
d. there is not sufficient evidence to reject the claim \\( \mu = 49.7 \\).

Explanation:

In hypothesis testing, the null hypothesis \(H_0:\mu = 49.7\). When we reject the null hypothesis, it means that the sample data provides enough evidence against the null hypothesis.

Answer:

C. There is sufficient evidence to reject the claim \(\mu = 49.7\).
