Examine the data below showing the weights (in pounds) of randomly selected checked bags for an airline's flights on the same day. Click here for the data. Let µlul be the population mean pounds for International bags and µ2µ2 be the population mean pounds for Domestic bags. You are asked to test whether International bags are heavier than Domestic bags.

Round to 4 decimal places. C.) What is the critical value at the a = 0.01 level? If there are two critical values, enter the positive one. If there is one critical value you need to make sure it has the correct sign depending on what type of test it is. Round to 4 decimal places. D.) What do you conclude at the a = 0.01 level? Select one: Reject the null hypothesis Do not reject the null hypothesis E.) What is the p-value? Round to 4 decimal places. F.) What is the highest degree of confidence that you can say that international luggage is heavier than domestic luggage?. Round to two decimal places.
