Listed in the accompanying table are weights (lb) of samples of the contents of cans of regular Coke and Diet Coke. Assume that the two samples are independent simple random samples selected
from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) to (c).
Click the icon to view the data table of can weights.
a. Use a 0.10 significance level to test the claim that the contents of cans of regular Coke have weights with a mean that is greater than the mean for Diet Coke.
What are the null and alternative hypotheses? Assume that population 1 consists of regular Coke and population 2 consists of Diet Coke.
A. Ho: H1 H2
H₁: H₁>H₂
