Conduct each test at the α = 0.05 level of signiﬁcance by determining
(a) The null and alternative hypotheses,
(b) The test statistic,
(c) The critical value, and
(d) The P-value. Assume that the samples were obtained independently using simple random sampling.
Test whether p1 < p2.
Sample data: x1 = 109, n1 = 475, x2 = 78, n2 = 325
