Question

Quizplus · Accepted Answer

In a two-tailed test, the p-value is calculated by finding the probability of getting a z score as extreme as the test statistic in both tails of the distribution. For a z score of 1.47, the one-tailed probability is approximately 0.0708. Since it's a two-tailed test, this value is doubled, resulting in a p-value of approximately 0.1416.
