Answer 1

Answer:

Step-by-step explanation:

Since the mode of the given series is 36 and maximum frequency 16 lies in the class 3244 the modal class is 30 to 40 the missing frequencies X then I'll equals to 30 f 1 equals to 16 as 0 = 2 x 2 = 212 and X = 210 36 + 10 into 16 - X by 20 - X 36 equals to 30 + 10 into 16 - X by 2 into 16 minus x minus 12 36 - 30 equals to 10 into 16 - X by 20 - 66 by 1 equals to 10 into 16 minus x by 20 - x 10 into 16 - x = 26 20 - x 160 - 10 X equal to 120 - 6 x minus 10 X + 16 X equals to 120 - 160 - 4 x equals to minus 14 x equals to minus 40 by 4 equals to 10
