To compare the customer satisfaction levels of two competing companies, 174 customers of company 1 and 355 customers of company 2 were randomly selected and were asked to rate the companies as a five point scale. The survey results are summarized in the following table. Company 1 n = 174 X7= 3.51 S1 = 0.51 Company 2 n2 = 355 X2= 3.24 %3D S2 = 0.52 Test the hypothesis that the customer satisfactions about the two companies are same at the level of significance 0.05.
