Questions #6-#8 are based on the following sample of ages (in months) of 18 children at a day care: 36, 42, 18, 32, 22, 22, 25, 29, 30, 31, 19, 24, 35, 29, 26, 36, 24, 28 The median age of the children is... 29 28.2 30.5 28.5 31 The interquartile range for this data set is... 8 12 16 20 24 The standard deviation of the age of children is... 41.24 11.33 10.20 6.42 6.24

Solution

Thus,

IQR = 8

Stdev = 6.42

Median = 28.5

Hope this helps.
