Problem 1BSC

Answer:

Step1 of 3:

We have the IQ scores of students in your statistics class or the IQ scores of a simple random sample taken from the general population.

Step2 of 3:

We need to check Which do we think has less variation: the IQ scores of students in your statistics class or the IQ scores of a simple random sample taken from the general population? Why?

Step3 of 3:

The IQ scores of a class of statistics students should have less variation, because those students are a much more homogeneous group with IQ scores that are likely to be closer together.
