Question

PLEASE HELP. NEED MOST APPROPRIATE COMPARISON OF THE SPREADS.

Answer 1

The interquartile range is given by:
Third quartile-First quartile
Thus
IQR of Town A:
First quartile=20
Third Quartile=40
hence
IQR=40-20=20°

IQR of Town B
First Quartile=20
Third Quartile=30
Hence
IQR=30-20=10

From the above calculations we conclude that the answer is:
A] The interquartile range (IQR) for town A, 20°,is greater than the IQR for Town B, 10
