Chapter 8, Problem 8.2-3(choose chapter or problem)
Let X equal the weight in grams of a Low-Fat Strawberry Kudo and Y the weight of a Low-Fat Blueberry Kudo. Assume that the distributions of X and Y are N(X , 2 X ) and N(Y , 2 Y ), respectively. Let 21.7 21.0 21.2 20.7 20.4 21.9 20.2 21.6 20.6 be n = 9 observations of X, and let 21.5 20.5 20.3 21.6 21.7 21.3 23.0 21.3 18.9 20.0 20.4 20.8 20.3 be m = 13 observations of Y. Use these observations to answer the following questions: (a) Test the null hypothesis H0: X = Y against a twosided alternative hypothesis. You may select the significance level. Assume that the variances are equal. (b) Construct and interpret box-and-whisker diagrams to support your conclusions
