Results of the 2011 Zagat Fast-Food Survey show Americans eat an average of 6.3 meals per month at fast-food chains. Suppose that in a follow-up study of 45 consumers in Oklahoma City and 55 consumers in Milwaukee you obtain the following results:

a. Formulate a hypothesis so that, if the null hypothesis is rejected, we can conclude that the number of meals eaten at fast-food chains by consumers in Oklahoma City is significantly less than the number of meals eaten at fast-food chains by consumers in Milwaukee.

b. What is the value of the test statistic?

c. What is the p-value?

d. Using α = .05, what is your conclusion?
