Following your analyses on age and pressure, you decide to exercise methodological control over the age variable. You therefore analyze the psychological and physiological correlates of blood pressure for 11 patients of the same age (45 years). You measure the average amount of calories consumed daily, the average number of hours of exercise per week and the patients' score on the Falcon stress scale (score out of 30, where 30 indicates a high level of stress). Using software, use a multiple linear regression analysis to examine the following data.

Calories	Exercise	Stress	Pressure
2461	7	20	122.41
2192	6	22	122.12
2317	11	21	124.06
2168	10	25	123.19
1876	5	26	133.73
2248	6	20	127.88
2492	3	24	134.92
2461	2	21	136.41
3117	1	24	139.62
2748	2	25	143.88
2892	0	24	143.43

1) What percentage of the variance in systolic blood pressure can be explained by patient calories, exercise, and stress? 2) Which predictor appears to have the least impact on blood pressure? Justify. 3) Report the "t" for the exercise variable; what does this "t" represent? 4) Interpret the results of this analysis and report them using an APA 5) Your patients want to improve their blood pressure but don't understand statistics; give them a simple conclusion about your analyses.
