Use the t-distribution. Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed.  
Claim: μ ≤ 125; α = 0.05. Sample statistics:   = 120; s =12; n = 28

Fail to reject H0; there is not enough evidence to reject the claim

Reject H0; There is enough evidence to reject the claim

Fail to reject H0; There is not enough evidence to support the claim
