The following regression model was estimated to forecast the value of the Malaysian ringgit (MYR): MYR t=a0+a1INCt-1+a2INFt-1+ut where MYR is the quarterly change in the ringgit, INF is the previous quarterly percentage change in the inflation differential, and INC is the previous quarterly percentage change in the income growth differential. Regression results indicate coefficients a0 = .005; a1= .4; and a2= -.7.

Based on the regression result, which of the following statement is correct?

(A) For a one-unit percentage change in the inflation differential, Malaysian ringgit is expected to change by .7% in the same direction, other things held constant.
(B) For a one-unit percentage change in the inflation differential, Malaysian ringgit is expected to change by .4% in the same direction, other things held constant.
(C) For a one-unit percentage change in the inflation differential, Malaysian ringgit is expected to change by .4% in the opposite direction, other things held constant.
(D) For a one-unit percentage change in the inflation differential, Malaysian ringgit is expected to change by .7% in the opposite direction, other things held constant.
(E) none of the above is correct

The hawthorne works was a large western electric factory with 45,000 employees. during the 1920s and 1930s, hawthorne works was the site of some well-known industrial studies. in one of the studies, researchers investigated the impact of different working conditions on worker productivity. prior to the start of the study, researchers secretly measured workers' productivity for several weeks. then researchers chose two workers, who then chose their own teams. the teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). for each of these changes in working conditions, the researchers measured the effect on productivity. for some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity.why did the researchers secretly measure the workers' productivity before creating the two treatment groups? a, to create similar treatment groups so that a cause-and-effect relationship could be establishedb, to draw conclusions about the productivity of all workers in the plant based on the test groupsc, to directly control for confounding variablesd, to provide a baseline for measuring worker productivity

Demand increases by less than supply increases. as a result, (a) equilibrium price will decline and equilibrium quantity will rise. (b) both equilibrium price and quantity will decline. (c) both equilibrium price and quantity will rise

Miller mfg. is analyzing a proposed project. the company expects to sell 14,300 units, plus or minus 3 percent. the expected variable cost per unit is $15 and the expected fixed cost is $35,000. the fixed and variable cost estimates are considered accurate within a plus or minus 3 percent range. the depreciation expense is $32,000. the tax rate is 34 percent. the sale price is estimated at $19 a unit, give or take 3 percent. what is the net income under the worst case scenario?
