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 right-tailed test is z=0.52 .
A) 0.6030 ; fail to reject the null hypothesis
B) 0.3015 ; reject the null hypothesis
C) 0.0195 ; reject the null hypothesis
D) 0.3015 ; fail to reject the null hypothesis

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 right-tailed test is  z=0.52 .
A)  0.6030 ; fail to reject the null hypothesis
B)  0.3015 ; reject the null hypothesis
C)  0.0195 ; reject the null hypothesis
D)  0.3015 ; fail to reject the null hypothesis

Quizplus · Accepted Answer

The P-value for a right-tailed test with z=0.52 is approximately 0.3015. Since 0.3015 > 0.05, we fail to reject the null hypothesis.
