# Identifying a Model and R2 Different samples are collected, and each sample consists of IQ scores of 25 statistics students. Let x represent the standard deviation of the 25 IQ scores in a sample, and let y represent the variance of the 25 IQ scores in a sample. What formula best describes the relationship between x and y ? Which of the five models describes this relationship? What should be the value of R2?

Step 1

In the study, the sample data are collected from the IQ scores of 25 statistics students. The standard deviation of the IQ scores represents x, and the variance of the IQ scores represents y.

The variance is the square of the standard deviation. From the information, the standard deviation of the IQ scores represents x, and the variance of the IQ scores represents&n...
