Answer 1

The mean of the numbers is 13.1

Calculation of Mean

The mean of a set of number is the summation of the numbers divided by the total number of values in the set. The mean is the measure of central tendency.

To calculate the mean, we use the formula:

`(\sum fx)/(fx)`

`=(14+14+8+1+12+16+8+13+8+11+14+12+16+19+8+18+19+19+13+19)/(20)`

= 262/20

= 13.1

Therefore, the mean of the numbers is 13.1.
