In a study of starting salaries paid by two large corporations, Corporation A and Corporation B, two independent random samples were taken. For 14 new employees of corporation A, the mean starting salary was $37,940 with a standard deviation of $5,280. For 14 new employees of corporation B, the mean starting salary was $42,110 with a standard deviation of $8,560. Compute and use a 95% confidence interval for the difference in the mean starting salaries of the two corporations to select the best answer below. Assume that both populations are normally distributed. Choose one answer. A. We are 95% confident that there is no statistically significant difference in the mean starting salaries of the two corporations. B.
