Because it takes many years before newly planted orange trees bear fruit, the supply curve in the short run is almost vertical. in the long run, farmers can decide whether to plant oranges on their land, to plant something else, or to sell their land altogether. therefore, the long-run supply of oranges is much more price sensitive than the short-run supply of oranges. assuming that the long-run demand for oranges is the same as the short-run demand, you would expect a binding price ceiling to result in • surplus that is in the long run than in the short run.

Which is cheaper: eating out or dining in? the mean cost of a flank steak, broccoli, and rice bought at the grocery store is $13.04 (money.msn website, november 7, 2012). a sample of 100 neighborhood restaurants showed a mean price of $12.75 and a standard deviation of $2 for a comparable restaurant meal. a. develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean cost of a restaurant meal is less than fixing a comparable meal at home. b. using the sample from the 100 restaurants, what is the p-value? c. at a = .05, what is your conclusion? d. repeat the preceding hypothesis test using the critical value approach
