Conduct the following test at the alphaαequals=0.100.10 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the critical value. assume that the samples were obtained independently using simple random sampling. test whether p 1 not equals p 2p1≠p2. sample data are x 1 equals 28x1=28, n 1 equals 254n1=254, x 2 equals 38x2=38 and n 2 equals 301n2=301. (a) determine the null and alternative hypotheses. choose the correct answer below. upper h 0 : p 1 equals p 2h0: p1=p2 versus upper h 1 : p 1 greater than p 2h1: p1> p2 upper h 0 : p 1 equals p 2h0: p1=p2 versus upper h 1 : p 1 less than p 2h1: p1
