Conduct a test at the α equals=0.10 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling.Test whether p1 > p2. The sample data are x1=118, n1=249, x2=142, and n2=315.

Expert Solution

Using the P-value approach: with z = 0.547 The p-value is p = 0.2923, and since p = 0.2923 ≥ 0.1, it is concluded that the null hypothesis is not rejected.

Conclusion

It is concluded that the null hypothesis Ho is not rejected. Therefore, there is not enough evidence to claim that the population proportion p₁ is greater than p₂, at the 0.1 significance level.
