A public health researcher is interested in some factors that influence heart disease. In a survey of 68 randomly selected localities, he gathered data on the percentage of people in each locality who bike to work “Biking”, the percentage of people in each locality who smoke “Smoking”, and the percentage of people in each locality who have heart disease “Heart.Disease”. The researcher wants to find which explanatory variable will be a better predictor of the response variable, “Heart.Disease”. Investigate the relationship between the explanatory variables and response variable to help the researcher find the better predictor. 1) Interpret the scatterplot of “Biking” and “Heart.Disease” using trend, strength, and shape (form) in one complete sentence. 2) Interpret the scatterplot of “Smoking” and “Heart.Disease” using trend, strength, and shape (form) in one complete sentence
