Answer:
Step-by-step explanation:
a). Mean of the given data set =
= 28
b). x
32 32-28 = 4 16
28 28 - 28 = 0 0
18 18 - 28 = -10 100
40 40 - 28 = 12 144
22 22 - 28 = -6 36
= 296
c). Standard deviation =
=
= 7.69
d). Mean of the new set of weights =
= 34
Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).
