Explanation / Answer

the data values are = 10,13,21,24,29,29,37,38,41,45,45,50,57,65,7,8,9,106

a) mean = sum of all/ total numbers = 35.22

b) yes the mean represent the centre because it is the average of the data values

c) there are total 18 values

mean = 9th + 10th/2 = (29+37)/2 = 33

d) yes it represent the centre because it is close to the mean

d) mode = 29 , 45

both have the same frequency

and they are the typcal data entries
