Suppose the average return on asset a is 6.3 percent and the standard deviation is 7.5 percent and the average return and standard deviation on asset b are 3.4 percent and 3.0 percent, respectively. further assume that the returns are normally distributed. use the normdist function in excel® to answer the following questions

a. what is the probability that in any given year, the return on assets a will be greater than 9 percent? less than 0 percent?

b. what is the probability that in any given year, the return on asset b will be greater than 9 percent? less than 0 percent?

c-1 in a particular year, the return on asset a was −4.30 percent. how likely is it that such a low return will recur at some point in the future?

c-2 asset b had a return of 10.10 percent in this same year. how likely is it that such a high return on asset b will recur at some point in the future?

As a result of a labeling mistake at the chemical factory, a farmer accidentally sprays weedkiller rather than fertilizer on half her land. as a result, she loses half of her productive farmland. if the property of diminishing returns applies to all factors of production, she should expect to seea. a decrease in the marginal productivity of her remaining land and an increase in the marginal productivity of her labor. b. an increase in the marginal productivity of her remaining land and an increase in the marginal productivity of her labor. c. an increase in the marginal productivity of her remaining land and a decrease in the marginal productivity of her labor. d. a decrease in the marginal productivity of her remaining land and a decrease in the marginal productivity of her labor.

6. why the aggregate supply curve slopes upward in the short run in the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. several theories explain how this might happen. for example, the misperceptions theory asserts that changes in the price level can temporarily mislead firms about what is happening to their output prices. consider a soybean farmer who expects a price level of 100 in the coming year. if the actual price level turns out to be 90, soybean prices will , and if the farmer mistakenly assumes that the price of soybeans declined relative to other prices of goods and services, she will respond by the quantity of soybeans supplied. if other producers in this economy mistake changes in the price level for changes in their relative prices, the unexpected decrease in the price level causes the quantity of output supplied to the natural level of output in the short run.
