Step-by-step explanation:

The red line represents the line for women, while the blue line represents the line for men.

Age 45 is the middle of 40 and 45 on the x-axis.

The average number of awakenings during the night for 45 -year-old men ≈ 5

The average number of awakenings during the night for 45 -year-old women = 3

The difference = 5 - 3 = 2 times during the night.
