The following table describes the effect of wearing a mask on
the probability of contracting COVID- 19 from another person. Apply
the regression equation 𝑦 = 𝛽 + 𝛽 𝑥 + 𝜀 to the problem at hand.
6. # Masks
7. Contracting COVID-19
8. 0
9. 70%
10. 1
11. 5%
12. 2
13. 1.5%
What is the dependent variable?
What is the independent variable?
Calculate the r correlation between the dependent and the
independent variables. What do you
learn?
Use the table to estimate the model 𝑦̂ = 𝛽0 + 𝛽0 + 𝑒.
What is the slope?
Interpret the meaning of the slope.
What is the intercept?
Interpret the meaning of the intercept.
Calculate 𝑅2 for this model. What do you learn about the
goodness of fit?
Add a column with residuals to the table. What can you learn
from the residuals about the goodness of
fit?
Describe what you have learned from this exercise about the
importance of wearing a mask in
public settings.
