Quizplus · Accepted Answer

The p-value for a z-statistic of 0.50 is 0.3085. This is the probability of getting a z-statistic as extreme as or more extreme than 0.50, assuming that the null hypothesis is true. Since the p-value is greater than 0.05, we fail to reject the null hypothesis and conclude that there is not enough evidence to support the alternative hypothesis.
