Answer 1

Answer #1

a)
Calculate the mean, median, and the standard deviation. rl
x_bar = 535

since the data can be arranged in the ascending order and split these data into two equal parts. 8th rem is the middle term (median) since there are 15 (odd) terms and that is: 587

527,552,564,492,545,507,540,587,517,565,587,498,552,492,500

standard deviation is given by

Sd = 33.08

b)
Coefficient of skewness
3(M -M ,A-M)
Sk = 3(535 - 587)/ 33.08 = - 1.57
