Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis. a) one tail test, z- = 1.40, and a= 0.02 b) one-tail test, z: = -2.05, and a = 0.01 c) two-tail test, z; =2.80, and a = 0.02 d) two-tail test, z. = - 1.82, and a=0.10 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
