The Gibbs Baby Food Company wishes to compare the weight gain of infants
using their brand versus their competitor’s. A sample of 40 babies using the
Gibbs products revealed a mean weight gain of 7.6 pounds in the first three
months after birth. The standard deviation of the sample was 2.3 pounds. A
sample of 55 babies using competitors brand revealed a mean increase in
weight of 8.1 pounds, with a standard deviation of 2.9 pounds. At the 0.05
significance level, can we conclude that babies using the Gibbs brand gained
less weight?
