A magazine claims that the mean amount spent by a customer at Burger Stop is greater than the mean amount spent by a customer at Fry World. The results for samples of customer transactions for the two fast food restaurants are shown below. At a = 0.10, can you support the magazine's claim? Assume the population variances are equal. Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e) below. Burger Stop Fry World X, = $9.13 X2 = $8.50 5, = $0.78 52 = $0.68 n, = 17 n = 8 The null hypothesis, Ho Y The alternative hypothesis, H, (b) Find the critical value(s) and identify the rejection region(s).
