Independent random samples are selected from two populations and used to test the hypothesis H,,: (p, - p2) = 0 against the alternative H,: (p, - pZ) f 0. A total of 233 observations from population 1 and 312 from population 2 are analyzed by using MINITAB, with the results shown in the printout.

a. lnterpret the results of the computer analysis.

h. If the alternative hypothesis had been Ha:

- p2) < 0, how would the p-value change? Interpret the p-value for this one-tailed test.
