Answer

Explanation:

Step1: Find last summer's mode

The mode is the most frequent value. For last summer: 140, 220, 190, 180, 190. The value 190 appears twice, so mode = 190.

Step2: Find this summer's mode

For this summer: 150, 170, 150, 190, 180. The value 150 appears twice, so mode = 150.

Step3: Calculate mode difference

Subtract the two modes: $190 - 150 = 40$

Step4: Find last summer's range

Range = max - min. Last summer max=220, min=140. $\text{Range} = 220 - 140 = 80$

Step5: Find this summer's range

This summer max=190, min=150. $\text{Range} = 190 - 150 = 40$

Step6: Calculate range difference

Subtract the two ranges: $80 - 40 = 40$

Answer:

The modes differ by 40 and the ranges differ by 40.
