3. The following model is a simplified version of the multiple regression model used by BEST Econometrics Group to study the trade off between time spent sleeping and working to look at other factors affecting sleep: sleep %3D Bo + Вitotwrk + Bzeduc + Bзадe + Ma where sleep and totwork (total work) are measure in minutes per week and educ and age are measured in years. (i) If adults trade sleep for work, what is the sign of B1? (ii) What signs do you think B2 and ß3 will have? (iii) Using the data in SLEEP75.RAW, the estimated equation is sleep — 3, 638.25—.148totwrk — 11.13educ — 2.20аge, п %3 706, R? =. 113 If someone works five hours per week, by how manu minutes is sleep predicte d to fall? Is this a large tradeoff? (iv) Discuss the sign and magnitude of the estimated coefficient on educ. (v) Would you say totwrk, educ, and age explain much of the variation in sleep? What other factors might affect the time spent sleeping? Are these likely to be correlated with totwrk?
