Use the on to find the PvalueAlso use a 005 significance lev

Use the on 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) OA 0218, reject the null hypothesis OB 0.435; fail to reject the null hypothesis OG 0.218 fail to reject the null hypothesis OD 0435, reject the null hypothesis

Solution

Here alternative hypothesis shows that test is two tailed. Since z=0.78 so P value of the test is

p-value=2P(z>0.78)=0.435

Since p-value is greter than 0.05 so fail to reject the null hypothesis. option B is correct.
