Use a t-test to test the claim about the population mean mu at the given level of significance alpha using the given sample statistics. Assume the population is normally distributed.

Claim: munot equals28; alpha0.10Sample statistics: x overbar=27.4, s4.6, n=13

1)What are the null and alternative hypotheses?

2)What is the value of the standardized test statistic?

3)What is the P-value of the test statistic?

4)Decide whether to reject or fail to reject the null hypothesis.

a)Fail to reject H0. There is enough evidence to support the claim.

b)Fail to reject H 0. There is not enough evidence to support the claim.

c)Reject H 0. There is not enough evidence to support the claim.

d)Reject H 0. There is enough evidence to support the claim.
