Salary (in thousands of dollars) and league are shown in the accompanying table. In a test of the hypothesis that there is a difference in the mean salary of players in each league, one could not reject the null hypothesis that the mean salaries for the two leagues are the same, using a two-tailed test with a significance level of 0.05. Assume that the distributions are Normal enough to use the t-test. Complete parts a and b below. Click the icon to view the data table. a. If you found a 95% confidence interval for the difference between means, would it capture 0? Explain. The confidence interval would contain 0, because the test cannot conclude that the means are Baseball Salaries Full Data Set D X League Salary American National League 505.6 National Salary 2100 185 American 3250 National 500 National 1100 American 170 American 436.4 National 382 National 700 American 3250 American 62.5 National 340 American 1000 American 660 American 650 National National National 4033.3 National 735 American 3450 247.5 American 525 National 100 270 American 109 American 109 American 122 extbook American American 3350 62.5 National 515 American 3300 Clear all Check answer Save K A random sample of 30 professional baseball salaries from 1985 through 2015 was selected.
