Suppose you are interested in estimating how health affects productivity. Specifically, you are interested in the following regression: where Y, is a variable representing the income earned by person i, and X, is a variable representing the health of person i. Income is a fairly straightforward concept to capture. Health, however, is a more complex concept that can be measured in many different ways. For example, body mass index (BMI weight in kilograms, divided by height in meters squared) is...

Question 7 1 pts You could also estimate a regression with arrest likelihood as an outcome when the dummy variable for treatment as the regressor. (This regression estimates what is commonly called the intent to treat effect). What would the coefficient on treatment be for that regression? arresti-α0 + α!treatment

I need help from 9-11.
I calculated 7-8 below.
7)Alcohol Consumption (liters/person/year): 3
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.

How much alcohol can one consume before one's Blood Alcohol Content (BAC) is above the legal limit? An experiment was conducted at Gallaudet University to predict Blood Alcohol Content from the number of beers. A total of 50 volunteer college students (some men and some women) were assigned a certain number of beers to drink and then, after a half an hour, their Blood Alcohol (BAC) level was measured. To make this assignment simpler, we will only use the first...
