Answer:
(1) <em>Y</em>-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.
Step-by-step explanation:
Consider the Frequency table and Histogram provided below.
(1)
The <em>y</em>-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)
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)
Thus, the number of students who spent fewer than 2 hours a night studying is 8.
