Question

student's homework score is 420, what would be the predicted midterm score? 3. The following is a scatterplot of the liters of alcohol from drinking wine per death rates from heart disease per 100,000 people for each of 19 countries. The least regression line has been drawn in on the plot. -squares 300 250 200 150 100 50 Alcohol from Driaking Wine Based on the least-squares regression line we would predict that in a country where, per person, 7 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. 260. d. 700 Explain in detail how you arrived at your answer

Explanation / Answer

In a country where per person 7 litres of alcohol from wine is consumed then the predicted death rate from heart diseases per 100,000 would be around b. 100. This value can be read off by tracing the point on the Y-axis corresponding to the point 7 on the X-axis based on the line of best fit.

We can see that the value on the Y-axis comes up to 100 for a value 7 on the X-axis based on the line of best fit.s

So, the most appropriate predicted value is 100.
