Question

21. Multiple regression analysis uses (a) several dependent variables (b) several independent variables. (c) data from several time periods. (d) several error terms. 22. A regression estimates that q = 35-0.1x, where q is the quit rate and X is the number of employees at the firm. Both t-statistics are greater than 2. This indicates that doubling the number of employees from 50 to 100 will reduce the quit rate by: (a) 50 percentage points. (b) 5 percentage points. (c) 35 percentage points. (d) 10 percentage points. 23. If leisure is a normal good then an increase in non-labor income will cause desired hours of work to: (a) decrease. (b) increase. (c) stay the same (d) either decrease or increase.
