Some people took part in a game. The frequency how information about their core. Score Frequency 1 - 7 6 8 - 10 15 11 - 15 20 16 - 20 18 21 - 35 10 36 - 50 8 Etimate the mean. Give your anwer rounded to 2 decimal place

Using mean formula for given frequency, the estimate mean is 17.49 ..

Mean is defined as the ratio of sum of observations by the total number of observations.

we have given the discrete class interval so, first we find out the mid point of intervals and then proceed . Arrange the given data

intervals Mid-point(Xᵢ) frequency(f) fixi

1 -7 4 6 24

8 -10 9 15 135

11 -15 13 20 26

16-20 18 18 324

21-35 26 10 260

36 - 50 43 8 344

Sum of fᵢ Xᵢ= 24+135+260+260+324+344 =1347

Sum of frequency (fi) = 6+15+20+18+10+8 = 77

Using Mean formula for given frequency data is

Mean = (∑f X )/∑f= 1347/ 77 = 17.49

Hence, the estimate mean is 17.49 ( around two decimals ) .
