Let x equal the thickness of spearmint gum manufactured for vending machines. assume that the distribution of x is n(mu, sigma^2). the target thickness is 7.5 hundreds of an inch. we shall test the null hypothesis h_0: mu=7.5 against a two-sided alternative hypothesis, using 10 observations. let m denote the sample mean and s^2 denote the sample variance.
define the test statistic in terms of m and s.
