Use the side-by-side boxplots shown to complete parts (a) through (e). X 30 60 90 120 (a) What is the median of variable x? The median of variable x is . (Round to the nearest integer as needed.) (b) What is the third quartile of variable y? The third quartile of variable y is . (Round to the nearest integer as needed.) (c) Which variable has more dispersion? Why? O A. Variable x-the range of variable y is smaller than that of variable x. O B. Variable y-the interquartile range of variable y is larger than that of variable x. O C. Variable x-the interquartile range of variable x is larger than that of variable y. O D. Variable y-the range of variable x is smaller than that of variable y. O E. Both dispersions are equal.Use the side-by-side boxplots shown to complete parts (a) through (e) X y 30 60 90 120 (d) Describe the shape of the variable x. Support your position. Choose the correct answer below. O A. Skewed right-the median is right of center in the box and the left whisker is shorter than the right whisker. O B. There is not enough information to determine the shape of the variable x. O C. Skewed left-the median is left of center in the box and the left whisker is longer than the right whisker. O D. Symmetric-the median is the center of the box and the left and right whiskers are about the same length. (e) Describe the shape of the variable y. Support your position. Choose the correct answer below. O A. Skewed left-the median is right of center in the box and the left whisker is longer than the right whisker. O B. Symmetric-the median is the center of the box and the left and right whiskers are about the same length. O C. There is not enough information to determine the shape of the variable y. O D. Skewed right-the median is left of center in the box and the left whisker is shorter than the right whisker.A professor has recorded exam grades for 30 students in his class, but one of the grades is no longer readable. If the mean score on the exam was 82 and the mean of the 29 readable scores is 84, what is the value of the unreadable score? The value of the unreadable score is
