Question

1. A researcher wants to test a new drug in its ability to decrease the pulse rate for patients. The data are shown below for 6 patients: Data is also available in spss as HW7.sav

Patient	Dosage	Decrease in Pulse Rate
Amy	2	15
Betsy	1.5	9
Chris	3	18
Dorothy	2.5	16
Ethel	4	23
Frank	3	20

Now, I want to run a regression analysis to determine if there is a predictive relationship between the dosage and the decrease in the pulse rate of patients.

Which variable is the dependent variable (the one that is being predicted or the effect)?

Which variable is the independent variable (the one that is being used to predict or the cause)?

Make a statement about the cause and effect relationship that you will be estimating in regression:

I will be using ___________________ to predict the _________________ of patients

The resulting regression line is:

Describe the intercept of the regression equation

Describe the slope of the regression equation

Run a hypothesis test to determine if there is a significant regression between dosage and pulse rate. Test using an α = 0.05
