Question
Data on the weights (lb) of the contents of cans of diet soda versus the contents of cans of the regular version of the soda is summarized
to the right. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do
not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.01 significance level for both
parts.
My: Hy FH₂
OC. Ho: Hy #4₂
H₁: Hy <H₂
The test statistic, t, is (Round to two decimal places as needed.)
The P-value is. (Round to three decimal places as needed.)
State the conclusion for the test.
