Independent random samples are selected from two populations and are used to test the hypothesis H0:(μ1−μ2)=0H0:(μ1−μ2)=0 against the alternative Ha:(μ1−μ2)≠0.Ha:(μ1−μ2)≠0. An ­analysis of 233 observations from population 1 and 312 from ­population 2 yielded a p-value of .115.

a). Interpret the results of the test.
b). If the alternative hypothesis had been Ha:(μ1−μ2)<0,Ha:(μ1−μ2)<0, how would the p-value change? Interpret the p-value for this one-tailed test.
