The accompanying table contains the satisfaction rating for 10 traditional cellphone providers and 13 prepaid cellphone service providers. Assuming that the population variances from both types of cellphone providers are equal, is there evidence of a difference in the mean ratings between the two types of cellphone providers? (Use α = 0.05) Round to two decimal places as needed. a. What is the test statistic? b. What is/are the critical value(s)?

Does the quality of cell service vary between providers? The file CellService provides the cellphone ratings of AT&T and Verizon Wireless in 23 U.S. cities. (Data extracted from "Smart-Phone Shopping Guide;" Consumer Reports, January 2014, pp. 30-31.) At the 0.05 level of significance, is there evidence of a difference in mean cell service ratings between AT&T and Verizon Wireless? What assumption about the cellphone ratings is necessary to perform this test? Use a graphical method to evaluate the assumption made in (a): Construct and interpret a 95% confidence interval estimate of the difference in the mean cell service between AT&T and Verizon Wireless.
