A pitcher for a professional baseball team allows runs in the first nine games he starts this season. Let A be the set of the number of runs allowed by the pitcher in his first nine starts. In the tenth game he starts, he allows 9 runs. Let B represent the set of the number of runs allowed in all ten games he has started. Select the true statements. The median of A is the same as the median of B. The interquartile range of B is greater than the interquartile range of A. Including the runs allowed in the tenth game does not cause the spread of the data to change. The median of B is 1 run more than the median of A. The interquartile range of A is 1 less than the interquartile range of B.
