Exercise 3.23
from the given data, min = 10 and max = 20
Range = max - min = 20 -10 = 10
In given data, Q3 = 17 and Q1 = 12
Interquartile range = 17-12 = 15
Exercise 3.29
from the given data, min = 28 and max = 60
Range = max - min = 60 - 28 = 32
In given data, Q3 = 55 and Q1 = 45
Interquartile range = 55 - 45 = 10
b)
sample mean = 435/9 = 48.33
sample variance = 742/8 = 92.75
sample std. dev. = sqrt(92.75) = 9.63
c)
Same mean with different variance and standard deviation
