Question

During a 10 days period, Hari received the following number of phone calls each day 1, 2, 3, 9, 3, 5, 7, 7, 10, 7. The arithmetic mean of the median and mode of this set of data is:

Answer 1

Step-by-step explanation:

mean = (1+2+3+9+3+5+7+7+10+7)/10

mean = 5.4

median is the middle number of the series

1, 2, 3, 3, 5, 7, 7, 7, 9, 10 median is (5+7)/2 = 6

mode is the maximum number of times a number occured so here maximum number of times a number occured is 7

so mode is 7
