Solution

To calculate the mean number of books read, you need to multiply the number of students by the number of books each student read, then add all those products together to get the total number of books read. After that, divide the total number of books read by the total number of students. Here's how:

  1. Multiply the number of students by the number of books each group read:

    • 2 students read 2 books: 2*2 = 4 books
    • 9 students read 3 books: 9*3 = 27 books
    • 14 students read 4 books: 14*4 = 56 books
    • 10 students read 5 books: 10*5 = 50 books
  2. Add all those products together to get the total number of books read:

    • 4 + 27 + 56 + 50 = 137 books
  3. Divide the total number of books read by the total number of students (35):

    • 137 / 35 = 3.914

So, the mean number of books read is approximately 3.9 when rounded to the nearest tenth.
