Question

4).  We have price-per-can information for independent
samples of two soup varieties. Assume the
populations of prices each follow normal
distributions.
Find the 99% CI for the difference
between the two population means. Use df = 20,
if needed. Then use the CI to conduct a NATDRC
test of the claim of no difference in the population
means.

soup #1: n = 15, X-bar = 0.73, s = 0.05 (in $)
soup #2: n = 24, X-bar = 0.91, s = 0.03
