[sleepi = 3624 ? 0.1468 totworki ? 9.742 educi + 2.377 agei ? 0.00137 earnsi
n = 706 R2 = .114 ¯R2 = .109
where sleepi are minutes slept at night per week for individual i, totwrki are minutes worked per
week, educi are years of schooling, agei is the ith individual’s age in years, and earnsi are the ith
individual’s total earnings in a given year.

a) Interpret all estimated coefficients, except for the intercept. Recall the ceteris paribus assumption.
(b) Interpret the coefficient of determination, R2.
(c) Interpret the adjusted R2, ¯R2.
(d) How many degrees-of-freedom remain after this regression is estimated? Show your calculations.
(e) The standard error for totwrk’s coefficient 0.01682. Is this estimate statistically significant at
a = 0.05?
