Calculation of and interpretation based on the P-value is required in this problem. You will choose your own level of significance. After typing out a) and b), use scratch paper to identify all variables from the given information using the correct symbols (s, , , x-bar, n, p, , etc.), then go to the templates tab in the Unit 3 Excel Guide (part 1) and determine which template to use, based on the claim in the problem. Copy and paste the entire template (including title) to the right of the problem using the instructions in the blue-shaded area. Use cell references from the completed template to answer parts c) - g). Next, give the conclusion of your hypothesis test (choose "reject the null hypothesis" or "fail to reject the null hypothesis") based on the P-value and explain why you chose your conclusion. Finally, give an interpretive sentence. Follow examples given in the Unit 3 Excel Guide for correct wording. | |||||||||
