The mean age of professors at a university is 58.4 years. if a hypothesis test is performed, how should you interpret a decision that fails to reject the null hypothesis? a) there is sufficient evidence to support the claim μ-584. b) there is sufficient evidence to reject the claim μ= 58.4. c) there is not sufficient evidence to reject the claim μ-584. d) there is not sufficient evidence to support the claim μ=58.4.

B) There is sufficient evidence to support the claim μ=584

Step-by-step explanation:

Let be the population mean age of professors at a university.

As per given , we have

Null hypothesis :

If we fails to reject null hypothesis , it means that we need to accept it.

It means we have sufficient evidence that null hypothesis is true.

i.e. There is sufficient evidence to support the claim μ=584

Hence, the correct answer is A) There is sufficient evidence to support the claim μ=584.
