QuestionConduct the following test at the α=0.01\alpha=0.01 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 p1p2\mathrm{p}_{1} \neq \mathrm{p}_{2}. Sample data are x1=30,n1=255,x2=38\mathrm{x}_{1}=30, \mathrm{n}_{1}=255, \mathrm{x}_{2}=38 and n2=301\mathrm{n}_{2}=301. (a) Determine the null and alternative hypotheses. Choose the correct answer below. H0:p1=p2H_{0}: p_{1}=p_{2} versus H1:p1<p2H_{1}: p_{1}<p_{2} H0:p1=p2H_{0}: p_{1}=p_{2} versus H1:p1>p2H_{1}: p_{1}>p_{2} H0:p1=p2H_{0}: p_{1}=p_{2} versus H1:p1p2H_{1}: p_{1} \neq p_{2}

Studdy Solution
Our **test statistic** (z0.31z \approx -0.31) falls within the **critical values** (±2.576\pm 2.576).
Therefore, we *fail to reject* the null hypothesis.
There's not enough evidence to say there's a statistically significant difference between p1p_1 and p2p_2.
The correct hypotheses are H0:p1=p2H_0: p_1 = p_2 versus H1:p1p2H_1: p_1 \neq p_2.
