please answerr each questions;

also need APA reference

The manager of a hotel prides himself on the speedy check-in time. From his past years of experience, he believes the mean check-in time to be 131 seconds. Fawn, a long-time employee, is not so sure that is the case. In a sample of 15 check-ins, she found the mean check-in time of her sample to be 137 seconds with a standard deviation of 2 seconds. Run a hypothesis test to determine if the mean check-in time is different from 131 seconds. Alpha = 0.05

Preliminary questions: (1-9)

1. What is the mean of the population?

2. What is the mean of the sample?

3. What is the sample size?

4. Is this a one-tail or a two-tailed test? Why?

5. What would the null hypothesis be?

6. What would the alternative hypothesis be?

7. Would you solve for z or t? What formula would you use?

8. Let's pretend you found that the p-value was 0.06. Would you reject or fail to reject your null hypothesis? Why? What's the rule?

9. Let's pretend you failed to reject your null hypothesis. What would your conclusion be about the mean of the population?
