Extracted text: Frito-Lay produces a 10 ounce family size bag of the regular potato chips and a 9.5 ounce family size bag of wavy potato chips. Both of these bags are sold for the same price. A researcher wants to test the claim that there is really a difference in the mean weight of bags for the two types of potato chips despite being listed for two different weights? Random samples of 18 bags of each variety were selected and you may assume each sample was selected from a very large population. The data set is called "Regular and Wavy Potato Chips Weights." a) What is the parameter of interest? Choose one of the following symbols u (the population mean); µD (the mean difference from paired (dependent) data); µi – µ2 (the difference of two independent means); and describe the parameter in context of this question in one sentence.
