Answer

Explanation:

Step1: Calculate last - summer average

The sum of pages last summer is (140 + 220+190 + 180+190=920). The average is (\frac{920}{5}=184).

Step2: Calculate this - summer average

The sum of pages this summer is (150 + 170+150 + 190+180 = 840). The average is (\frac{840}{5}=168). So option A and C are incorrect.

Step3: Calculate last - summer range

The highest value last summer is 220 and the lowest is 140. The range is (220 - 140=80).

Step4: Calculate this - summer range

The highest value this summer is 190 and the lowest is 150. The range is (190 - 150 = 40). Since (80>40), the number of pages in each book varied more last summer than this summer.

Answer:

The number of pages in each book varied more last summer than this summer.
