a sample of 30 3-5 year old children were asked to count out loud. The highest number of numbers that a child can count before making an error was recorded and shown below numbers countted: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 1 5 16 number of children frequency :0 0 0 2 2 0 3 1 2 5 0 1 1 4 5 4 (a) what is number(s) did most 3-5 year old children (b) count up to ? (b) what is the median number of numbers to which 3-5 year old children can count up? (c) whar is the mean number to which 3-5 year old can count? sum of x= ? n= ? answer for mean is = ? (d) what is the standard deviation for which the number of numbers can count up to ? sum of(x square)= (sum of x) squared = final answer for the standard deviation is =?
