Step 1. Calculate the total number of books read by the students.
In the table we have the number of students and the number of books that those students read, for example:
2 students read 2 books per student -->2(2) = 4 books
We will do this for all of the rows in the table:
10 students read 3 books per student --> 10(3) = 30 books
16 students read 4 books per student --> 16(4) = 64 books
8 students read 5 books per students --> 8(5) = 40 books
Adding all of the books:
[tex]4+30+64+40=138[/tex]
138 books in total.
Step 2. Calculate the mean number of books read.
To calculate the mean we divide the total number of books by the number of students:
[tex]\frac{138}{36}[/tex]
The result of this division is:
[tex]3.8[/tex]
The mean of books read is 3.8
Answer: 3.8
