Chapter 9

Test the hypothesis level that orange and brown M&Ms weigh the same. Use the 0.5 significance level.
Test the hypothesis that blue M&Ms are no heavier or no lighter than the other colors using a 0.05 significance level. Hint: create a new variable that separates the sample into two groups, blue and not blue. This is probably best done by choosing Transform>Recode>Into different variables…

Find the correlation between weight and each of the variables age, headlen, headwth, neck, length, and chest. Which variable is the most correlated with weight? Which is least correlated?
Determine the regression equation predicting the weight from the variable chest. What is the regression equation? What percent of the total variation of the variable weight did the variable chest explain?
Use a 98% prediction interval to predict the weight of a bear with a chest measurement of 60 inches.
Determine the multiple regression equation predicting the weight from the variables, neck and chest. What is the multiple regression equation? What is the adjusted coefficient of determination associated with this regression equation? What percent of the total variation of the variables weight does the multiple regression equation explain?
