Question

Question 18 (4 points) 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). The test statistic in a two-tailed test is z = -1.63. 1) 0.9484; fail to reject the null hypothesis 2) 0.1032; fail to reject the null hypothesis 3) 0.0516; fail to reject the null hypothesis 4) 0.0516; reject the null hypothesis

Answer 1

Solution :

=> Answer :- Option 2) 0.1032; fail to reject the null hypothesis

Given that significance level α = 0.05 and

=> The test statistic in a two-tailed test is Z = -1.63

=> The P-value is = 0.1032

=> p-value > 0.05 then fail to reject the null hypothes
