A one-sample z-test for a population mean is to be performed. Let z 0 denote the observed value of the test statistic, z. Assume that a two-tailed test is being performed. True or false: If z0 is negative, the P-value is twice the area under the standard normal curve to the right of z0. 2) A) True B) False
Option - B) False
P-value = 2 * P(Z < z0)
The P-value is twice the area under the standard normal curve to the left of z0.
