  1. Assume that you plan to use a significance level of α = 0.05 to test 5)

    the claim that p1 = p2. Use the given sample sizes and numbers of

    successes to find the P-value for the hypothesis test, and make a conclusion addressed to the claim.
    n1=100 n2=100

    x1 = 38 x2 = 40

Please rate. Thanks.

We will use 2 sample proportion test :

Below is the minitab output. :

P value = 2 * P(T.S < -0.28995)

From z table, P (T.S.< - 0.028995) = 0.385927

Thus P value = 2 * (0.385927) = 0.778154

Since p value is > 0.05, we fail to reject Null hypothesis and conclude that data is not providing sufficient evidence to say that both the population proportions are different.
