(b) How many hours per week do students study?
(c) How many calories do students consume per day?
Step-by-Step Solution
VerifiedPart (a) Bar graph is used here.
Part (b) Histogram can be used to find the number of hours.
Part (c) Dot-plot is used to fin the number of calories.
Radio stations are most popular with students.
The number of hours the students would study.
The number of calories the students would consume per day.
A histogram is a graphing tool that is often used. It's used to summarize data that are either discrete or continuous and measured on an interval scale. It's commonly used to demonstrate the key aspects of data distribution in a user-friendly manner.

The amount of time the pupils would spend studying. The histogram can be used to determine how many hours per week children study because it examines quantitative variables in terms of frequency and relative frequency.
The number of calories consumed by the kids on a daily basis.
A dot-plot, which is a quantitative variable measured on a number line, can be used to investigate how many calories kids ingest every day.
