Problem 2
Hypothesis Testing
Suppose you are interested in the effect of neighborhood crime incidents on high school
graduation rates. You run the following regression model:
Graduation; ßo+ß₁Crime; +ɛ¿
=
You would like to test whether the neighborhood crime incidents have a statistically
significant effect on high school graduation rate at the 5% level of significance (α = 0.05).
You estimate the model and find that B₁ = -0.04 and se (B₁) = 0.008.
a. Write down the null hypothesis and alternative hypothesis. (4 points)
b. Calculate thet statistic of B₁. (5 points)
C. What is the critical value of thet statistic for the 5% level of significance? (2
points)
d. Calculate the 95% confidence interval for the coefficient on Crime? (6 points)
e. Based on your answers to the questions b, c, and d, do you reject or fail to reject the
null hypothesis you defined in question a? Justify your answer. (5 points)

f. Isẞ₁ statistically significant at the 5% level? (3 points)
Problem 1
Endogeneity & Bias
The ACT (an abbreviation of American College Testing) is a standardized test used for college
admissions in the United States.
Suppose you are interested in whether ACT preparation improves ACT scores. Consider the
following model:
ACT=B+B Preparation,+e;
where Preparation measures the number of hours spent on ACT preparation and ACT is
ACT scores. Each student is denoted by the subscript i.
Suppose you estimate = - 21 andß₁
= 0.9.
a. What is the dependent variable? What is the independent variable? (3 points)
b. How do you interpret ẞ = 21 in this context? (4 points)
0
C.
How do you interpretß₁ = 0.9 in this context? (4 points)
1
d. Describe a scenario which can cause the independent variable to be endogenous. (4

- Consider the market for electricity. Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.
