We Are Testing the Hypothesis That the Proportion of Winter-Quarter

question 100

Short Answer

We are testing the hypothesis that the proportion of winter-quarter profit growth is more than 2 percent greater for consumer industry companies (CON) than for banking companies (BKG). At α = .10, given that = .20, = .14, n_CON = 300, and n_BKG = 400, calculate the estimated standard deviation for the model.
