The ages of the eight-member school board are listed below. 28, 40, 34, 46, 60, 34, 51, 57 if a is equal to the median age of the group and b is equal to the mode of the group/s age, what is the value of a-b? (1 point)
From the set of data given: 28,40,34,46,60,34,51,57 re-arranging the above in ascending order we get: 28, 34,34, 40, 46,51,57,60 The mode of the numbers is 34 the median is: (40+46)/2=43 hence the median, a=43 the mode, b=34 therefore: a-b=43-34=9 Answer: 9
