2599 You're a sociologist studying whether grocery prices are different in the inner cities than they are in the suburbs. To investigate this, you pick a random set of items (a basket of goods), and then send shoppers to buy these items at an inner city (IC) grocery, and also at a suburban (SU) grocery. You pick 25 different baskets of goods, so your secret shoppers buy 25 baskets, once at the inner city store, and once at a suburban store. Prices could be higher in the inner city because of discrimination, or they could be higher in the suburbs because of the greater disposable income. Use Excel to test the research hypothesis that inner city prices are different than the suburb's prices. The null hypothesis is that inner city prices are equal to suburban prices. You test at the alpha = 0.01 significance level. What do you conclude? Are prices the same? Who has higher prices? Group of answer choices You do not reject the null hypothesis. Grocery prices are the same in the inner…
