The Gibbs Baby Food Company wishes to compare the weight gain of infants using its brand versus its competitor’s. A sample of 40 babies using the Gibbs products revealed a mean weight gain of 3.5 kilograms (kg) in the first three months after birth. For the Gibbs brand, the standard deviation of the population is 1.05 kg. A sample of 55 babies using the competitor’s brand revealed a mean increase in weight of 3.7 kg, with a standard deviation of 1.3 kg. Can we conclude that babies using the Gibbs brand gained less weight? Choose an appropriate significance level. Compute the p-value, and interpret it.
