Identifying individuals with a high risk of alzheimer's disease usually involves a long series of cognitive tests. However, researchers have developed a 7 minute screen, which is a quick and easy way to accomplish the same goal. The question is whether the 7 minute screen is as effective as the complete series of tests. The address this question, Ijuin administered both tests to a group of patients and compared the results. the following data represent results similar to those obtained in the study.

Patient 7 minute screen cognitive series

A 3 11

B 8 19

C 10 22

D 8 20

E 4 14

F 7 13

G 4 9

H 5 20

I 14 25

Use SPSS only and change the directions to the following:

A) Construct a scatterplot, and

B) Do all steps in hypothesis testing to examine the relationship between the 7 minute screen and the cognitive series, and

C) Find the regression equation to predict the cognitive series score from the 7 minute screen score using SPSS. Be sure to write out the equation by hand using the variable names
