9.2.2 Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis. a) one-tail test, zx = 1.60, and -002 c) two-tail test, zx = 2.10, and = 0.02 Click here to view page 1 of the cumulative probabilities for the standard normal distribution Click here to view page 2 of the cumulative probabilities for the standard normal distribution. b) one-tail test, z. =-2.05, and = 0.05 d) two-tail test, z-=-1.86, and = 0.01 a) The p-value is (Round to four decimal places as needed.)Explanation / Answer
A. P-value= p(Z>1.60)=0.0548
Do not reject the null hypothesis
B. P-value=P(Z<-2.05)=0.0202
Reject the null hypothesis
C. P-VALUE=2×P(Z>2.10)=2×0.01786=0.03572
Do not reject the null hypothesis
D. P-VALUE=2×P(Z<-1.86)=2×0.031443=0.0629
Do not reject the null hypothesis
