Answer:

(1) Y-axis: number of students who spends respective hours studying.

(2) The number of students who spent 2 or more hours studying is 12.

(3) The number of students who spent fewer than 2 hours a night studying is 8.

Explanation:

Consider the Frequency table and Histogram provided below.

(1)

The y-axis of the histogram represents the frequencies or the number of students who spends respective hours studying.

(2)

Compute the number of students who spent 2 or more hours studying as follows:

N (X ≥ 2) = n (X = 2 - 2:59) + n (X = 3 - 3:59) + n (X = 4 - 4:59)


=7+4+1\\=12

Thus, the number of students who spent 2 or more hours studying is 12.

(3)

Compute the number of students who spent fewer than 2 hours a night studying as follows:

N (X < 2) = n (0 - 0:59) + n (1 - 1:59)


=3+5\\=8

Thus, the number of students who spent fewer than 2 hours a night studying is 8.
