Question

Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).
-$\text { With } \mathrm { H } _ { 1 } : \mathrm { p } \neq 0.221 \text {, the test statistic is } \mathrm { z } = 2.21 \text {. }$

A) 0.0272; fail to reject the null hypothesis
B) 0.0136; fail to reject the null hypothesis
C) 0.0272; reject the null hypothesis
D) 0.0136; reject the null hypothesis

The P-value for a two-tailed test with z = 2.21 is 0.0272. Since 0.0272 is less than the significance level of 0.05, we reject the null hypothesis.

Use the Given Information to Find the P-Value With H1:p≠0.221, the test statistic is z=2.21. \text { With } \mathrm { H } _ { 1 } : \mathrm { p } \neq 0.221 \text {, the test statistic is } \mathrm { z } = 2.21 \text {. } With H1​:p=0.221, the test statistic is z=2.21.
