Option c

Step-by-step explanation:

Given the particulars about number of books read by males and females in a high school in the past year.

Males had a mean of 8.4 with std dev 2.3

Females had a mean of 5.9 and std dev 1.8

Sample size was 107 for males and 120 for females

Mean difference between boys and girls = 8.4-5.9 = 2.5

Std error for difference =0.260

For 95% confidence interval

Margin of error =1.96(STd error)

= 1.96(0.260)

=0.51

Hence confidence interval for difference of means Males - Mean females

= (1.99,3.01)

Since mean difference is positive males read more books than females

There is a 95% probability that males seniors at this high school read between 1.99 and 3.01 more books than females

this is answer of 144 cubic meters
