Aresearcher wants to prove that there is a difference in the average life spans between men and women in japan. let mu1 = average life span of japanese women and mu2 = average life span of japanese men. a random sample of 10 women showed an average lifespan of 83 years, with a sample standard deviation of 7 years. a random sample of 10 men showed an average lifespan of 77 years, with a sample standard deviation of 6.4 years. assume that life spans are normally distributed and that the population variances are equal. if alpha = .05 and the null hypothesis is mu1 – mu2 = 0, what is (are) the critical value(s) for the hypothesis test?
