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
