Q1 In a test of a weight loss program, weights of 40 subjects are recorded before and after the program. Assume that the before/after weights result in r = 0.876.
Is there sufficient evidence to support a claim of a linear correlation between before/after weights?
Does the value of r indicate that the program is effective in reducing weight? Why or why not?
Q2 Research Dell Corporation and Hewlett Packard. Analyze each company's competitive strategy. Are they really in competition with each other? If so, how? Which company is the better competitor? Why? Which has the best chance for a successful future? Why?
