A random sample of high school seniors took a literacy test before graduation. A comparison of scores for the test showed that women scored significantly higher on average (p-value = 0.017) than men on the literacy test. What does the p-value in this statement tell us? If there were actually no difference in the mean literacy scores for all men and women at the high school, the probability of observing a difference between the two group means as large or...
