Unit 10 notes Fall23

In a simple linear regression prediction equation, the slope is defined as which of the following? The slope is the value of X when Y = 0. For a one-unit change in Y (the criterion), there will be a slope-unit change in X (the predictor) For a one-unit change in X (the predictor), there will be a slope-unit change in Y (the criterion) The slope is the value of Y when X = 0.

Describe regression variation in terms of variation in Y.

A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking related to the risk of strokes. The data file “Stroke.xslx” includes a portion of the data from the study. The variable “Risk of Stroke” is measured as the percentage of risk (proportion times 100) that a person will have a stroke over the next 10-year period.   Regression Analysis As Image:  1) Based on the simple regression analysis output, write the estimated regression equation.   2) What is the correlation coefficient between Risk of Stroke and Age? How do you find i
