Question

A random survey of a small group of high school students collected information on the students' ages and the number of books they had read in the past year.

a) What is the average age of the students surveyed?
b) How many students participated in the survey?
c) What is the most common number of books read?
d) How many students had read no books?

Answer 1

To find the average age of the students surveyed, add up their ages and divide by the total number of students. The number of students who participated in the survey can be determined by counting them. To find the most common number of books read, identify the number that appears most frequently. To find the number of students who had read no books, look for the count of students who reported reading zero books.

Step-by-step explanation:

a) To find the average age of the students surveyed, you would add up the ages of all the students and divide by the total number of students:

Average Age = Sum of Ages / Number of Students

b) The number of students who participated in the survey can be determined by counting the total number of students surveyed.

c) To find the most common number of books read, you would analyze the data collected and identify the number that appears most frequently.

d) To find the number of students who had read no books, you would look for the count of students who reported reading zero books in the past year.
