Question

I need help from 9-11.
I calculated 7-8 below.


7)Alcohol Consumption (liters/person/year): 3

The following table presents data on wine consumption (in liters per person per year) and death rate from heart attacks (in deaths per 100,000 people per year) in 19 developed Western countries. WINE CONSUMPTION AND HEART ATTACKS Alcohol Heart disease Alcohol from wine Deaths Heart disease Country Australia Austria Belgium Canada from wine Deaths 211 167 131 191 220 297 71 211 300 107 Country Netherlands New Zealand Norway Spain Sweden Switzerland United Kingdom United States West Germany 2.5 3.9 2.9 1.8 167 266 6.5 1.6 86 207 115 285 199 172 Finland France Iceland Ireland Italy 0.8 0.8 0.7 7.9 1.2 Answer each question/complete the tasks. (point value is in parentheses) 1. What is the explanatory variable and what is the response variable? (2) 2. Make a complete scatterplot of the data. (3) 3. Does it appear that there is a linear relationship between alcohol consumption and heart attacks? Is there a positive association or negative association? (2) 4. Compute the equation for the least squares regression equation and the correlation coefficient. (3) 5. Write sentences that interpret the slope and y-intercept of the LSRL. (4) 6. Superimpose the regression equatipn on the scatterplot. (1) 7. Predict the rate of heart attacks for a country where the average wine consumption is 3 liters/person'year. (2) 8. Would it be appropriate to try to predict the death rate from heart attacks for Estonia where the per capita wine consumption is 15 liters/year? Why or why not? (2) 9. What is the explained variation for this data? Interpret your result. (3) 10. Create a residual plot and comment on what you see. (4) 11. Is there statistical evidence that a linear relationship exists between wine consumption and the occurrence of heart attacks? Conduct an appropriate test. (4)

Heart disease = 260.56-22.969(3)

                        = 191.653
8) Alcohol Consumption (liters/person/year): 15

Heart disease = 260.56-22.969(15)

                        = -83.975

It wouldn’t be appropriate because the heart disease is in -83.975.

Answer 1

Ang = -83.17 eart disease, is in-43.9ヌ D We know the占pAz0-1i the amount t variation in heart death yate While. Atteng model, then ek oton oy residual lot, so click on ib there i n0 any pottem as such so vecidual are randomhe disbibuted
