The average (mean) number of hours spent on the computer is equal to 4.7 hours.
<h3>What is an arithmetic average?</h3>An arithmetic average is also referred to as mean and it can be defined as a ratio of the sum of the total number in a data set to the frequency of the data set.
<h3>How to calculate the mean?</h3>Mathematically, the arithmetic average for a given data set can be calculated by using this formula:
Average = [F(x)]/n
Next, we would calculate the arithmetic average for the number of hours spent on the computer as follows:
F(x) = 1(3) + 2(6) + 3(11) + 4(25) + 5(18) + 6(16) + 7(7) + 8(4) + 9(1)
F(x) = 3 + 12 + 33 + 100 + 90 + 96 + 49 + 32 + 9
F(x) = 424.
For the total number of students, we have:
n = 3 + 6 + 11 + 25 + 18 + 16 + 7 + 4 + 1
n = 91
Substituting the parameters into the formula, we have;
Average = 424/91
Average = 4.7 hours.
