Question
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 = 0.05, 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
X2 = $7.51
X1 = $8.14
S1 = $0.84
S2 = $0.79
n = 13
n2 = 11
Select the correct rejection region(s) below.
O A. t< - to
O B. - to <t<to
OC. t< - to, t> to
O D. t>to
(c) Find the standardized test statistic.
