D Question 10 10 pts Estimation by OLS using heteroskedasticity-consistent standard errors results in the following output: GPA; = 3.2 + 0.105X; + 0.12FEMALE; + 0.1 INCOME; (0.1) (0.05) (0.04) (0.03) where the numbers in parentheses (below the coefficients) are the robust standard errors. The treatment effect is 0.105, so that access to a laptop is expected to increase GPA by 0.105 points. Let's test whether or not this effect is statistically different from zero. The null hypothesis is Ho : B1 = 0. The alternative hypothesis is H1 : B1 # 0. The t-statistic is [ Select ] , and therefore we [ Select ] Ho at a 5% level. The p-value of this test is [ Select ] and therefore we [ Select ] Ho at a 1% level. What is the difference in predicted GPA between a male student who was lent a laptop and a female student who was not lent a laptop but has the same family income as the male student? [ Select ]Questions 9-15 Laptop access and GPA. Based on a random sample of 500 high-school students without laptops, a non-profit organization randomly lends laptops to 250 of them for the fall semester. A researcher wants to investigate whether being lent a laptop affects a student's grades, and collects data on the students' GPA for the Fall semester
