## Growth Hormone and

our UCLA Population

## For an example of a two parameter test involving dependent variables, we shall conduct experiments with our sample of the UCLA student population from previous lessons,whose heights are listed below:

## Student Height in Inches (before treatment)

## 59

## 62

## 63

## 63

## 64

## 64

## 64

## 65

## 65

## 66

## 71

## 71

## 72

## 72

## 72

## 73

## 74

## 76

## 77

## We have subjected the group of 32 students to an experimental growth hormone Laxon, a derivative of processed primate pituitary glands. After one month, we survey their heights again, and obtain the following results:

## Student Height in Inches (after treatment)

## 58

## 62

## 74

## 72

## 73

## 73

## 76

## 75

## 78

## The first step is to calculate the differences between the ordered pairs.
