-A company has two branches, one on the East Coast and the other on the West Coast. The mean daily sales of the company on the East Coast, when observed on 100 days, were found to be P250,000 with S1=P35,000. For the company on West Coast, when observed on 200 days, the mean daily sales were P245,000 with S2=P25,000. At the 5 percent level of significance, do the two branches differ in their true mean daily sales? (Assume that the sales in the two branches are normally distributed).
