Answer

The average is really close to the population mean IQ.

Work Step by Step

We count the average by adding the data together and dividing it by the number of data: 96+89+87+87+101+103+103+96+127+126+101+96+93+88+94+85+97+114+113+124=2020. 2020/20=101, which is really close to the population mean IQ.
