     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.
