Question

the following is a scatterplot of the liters of alcohol from drinking wine per person and the death rates from heart disease per 100,000 people for each of 19 countries. the least - squares regression line has been drawn in on the plot. based on the least - squares regression line, we would predict that in a country where (per person) 2 liters of alcohol from wine is consumed, the death rate from heart disease per 100,000 people would be about: a. 50. b. 100. c. 225 d. 150

Explanation:

Step1: Locate 2 on x - axis

Find the value of 2 liters of alcohol from drinking wine on the x - axis of the scatter - plot.

Step2: Read corresponding y - value

Move vertically up from x = 2 until intersecting the least - squares regression line, then move horizontally to the left to read the corresponding value on the y - axis (death rate from heart disease per 100,000 people). The value is approximately 225.

Answer:

C. 225
