Question
3. The following model is estimated: sleep = 3840.83 - 0.163totwrk + 11.71educ + 8.70age +0.128age? + 87.75male, I (235.11) (0.018) (5.86) (11.21) (0.134) (34.33) n = 706, R = 0.123 The variable sleep is total minutes per week spent sleeping at night, totwrk is total weekly minutes spent working, educ and age are measured in years, and male is a gender dummy. (a) All other factors being equal, is there evidence that men sleep more than women? Test the null hypothesis that men sleep the same amount of time as women against the alternative hypothesis that men sleep more than women at 5% significance level. (b) Is there a statistically significant tradeoff between working and sleeping? What is the estimated tradeoff?
