One hundred students in a statistics course kept track of the time they spent on social media over the weekend. Each student recorded his or her time rounded to the nearest minute, so each observation is a whole number. The data are presented in the form of a frequency histogram. 26 25- 20 20- 16 15 14 12 10- 120 150 I80 210 30 Minutes on social media Each interval on the histogram contains the left endpoint, except for the last bar, which contains both the left and right endpoints. Give the lower and upper bound for the median number of minutes spent on social media over the weekend by the students enrolled in the class. The lower bound is the largest number that is less than or equal to the median, and the upper bound is the smallest number that is greater than or equal to the median. lower bound = 60 upper bound = 85 Kouanbasg
