Independent random samples are selected from two populations and are used to test the hypothesis h0: (μ1−μ2)=0 against the alternative ha: (μ1−μ2)≠0.. an analysis of 234 observations from population 1 and 312 from population 2 yielded a​ p-value of 0.113 . complete parts a and b below. a). interpret the results of the test. b). if the alternative hypothesis had been ha: (μ1−μ2)< 0, how would the p-value change? interpret the p-value for this one-tailed test.
