Question 24 In this problem we find the standard deviation of the data shown in the frequency table below: X f X . f ( X - 1 )2 . f 4 14 5 10 11 7 20 8 10 We begin by completing the third column of the table. Then recall that for grouped data, A = EX . f N H = (round to two decimals) Next we complete the fourth column of the table. Round each value to two decimals. Finally, o = E(x - 1)2 . f N 0 = (round to two decimals)Age (x) 4 40 5 24 6 59 7 41 8 37 9 39 10 53 11 47 The table gives the ages for every child at a school. Find the population standard deviation for the age of chidren at the school. Round the mean to two decimals before doing any calculations, and then round your answer to two decimals
