A company that produces top-of-the-line batteries claims that its batteries are good, on average, for more than 65 months. A consumer protection agency tested 25 such batteries to check this claim. It found that the mean life of these 25 batteries is 63.4 months, and the standard deviation is 3 months. If we test the company's claim at a 5% significance level, what is the p-value? Assume normality. 0.0135 0.9933 0.0067 0.9962
