Test the claim about the population mean $\mu$ at the level of significance $\alpha .$ Assume the population is normally distributed. If convenient, use technology. Claim: $\mu=40 ; \alpha=0.05 ; \sigma=1.97$ Sample statistics: $\bar{x}=39.2, n=25$

Use a t-test to test the claim about the population mean μ at the given level of significance α using the given sample statistics. Assume the population is normally distributed. Claim: μ ≠ 25; α = 0.01 Sample statistics: x = 26.4, s = 4.8, n = 14
