a. Assuming that the population variances are equal and alphaequals0.05, is there evidence that the mean amount of potato chips eaten was significantly higher for the children who watched the celebrity-endorsed commercial?
Let population 1 be the weights of potato chips eaten by children who watched the celebrity-endorsed commercial and let population 2 be the weights of potato chips eaten by children who watched the alternative food snack commercial. What are the correct null and alternative hypotheses?
A.
Upper H 0: mu 1 minus mu 2less than or equals0
Upper H 1: mu 1 minus mu 2greater than0
B.
Upper H 0: mu 1 minus mu 2greater than or equals0
Upper H 1: mu 1 minus mu 2less than0
C.
Upper H 0: mu 1 minus mu 2equals0
Upper H 1: mu 1 minus mu 2not equals0
D.
Upper H 0: mu 1 minus mu 2not equals0
Upper H 1: mu 1 minus mu 2equals0
