Pages read: 10 + 20 + 10 + 20 + 40 + 10 + 20 + 30 = 160
mean= 160 ÷ 8
= 20.
hence, the mean number of pages that pallavi read every night is 20.

Mean = 20
Step-by-step explanation:
Pallavi read the following number of pages of her favorite novel each night before going to bed: 10, 20, 10, 20, 40, 10, 20, 30.
Mean = sum of observations / number of observations
= (10 + 20 + 10 + 20 + 40 + 10 + 20 + 30) / 8
= 160 / 8
= 20
Pallavi read 20 pages on average every night.
