Why are you growing yeast on both a URA- and TRP- plate? Question 5 options: The yeast are not expected to grow on the TRP- plate because we disrupted the Trp gene using CRISPR/Cas9; however, you want to make sure the yeast can grow on a plate to ensure it is viable and be able to use it for future studies. The yeast are expected to grow on the TRP- and you want to be able to use it for future studies. Growth on URA- plate ensures that you have disrupted the Trp gene using CRISPR/Cas9. You want to double check your pipetting.

Inventory Costs. Three firms carry inventories that differ in size. Firm A's inventory contains 2000 items, firm B's inventory contains 5000 items, and firm C's inventory contains 10,000 items. The population standard deviation for the cost of the items in each firm's inventory is $ \sigma=144 $. A statistical consultant recommends that each firm take a sample of 50 items from its inventory to provide statistically valid estimates of the average cost per item. Employees of the small firm state that because it has the smallest population, it should be able to make the estimate from a much smaller sample than that required by the larger firms. However, the consultant states that to obtain the same standard error and thus the same precision in the sample results, all firms should use the same sample size regardless of population size. a. Using the finite population correction factor, compute the standard error for each of the three firms given a sample of size 50 . b. What is the probability that for each firm the sample mean $ \bar{x} $ will be within $ \pm 25 $ of the population mean $ \mu $ ?

Suppose that Botoga completely specializes in the production of the good in which it has a comparative advantage, producing only that good. It will produce . Suppose also that Euclidia does not specialize and uses 18,000 hours of labor to produce jeans and 6,000 hours of labor to produce corn. It will produce pairs of jeans and bushels of corn. Suppose Botoga and Euclidia agree to trade with each other, exchanging 410 pairs of jeans for 1,230 bushels of corn. In particular, Botoga will export the goods it produces, and Euclidia will export the goods that Botoga does not produce. With trade, Botoga will jeans and corn. Euclidia will jeans and corn. When Botoga specializes and Euclidia still produces the combination of goods using 18,000 hours of labor to produce jeans and 6,000 hours of labor to produce corn, the total production of jeans becomes pairs per week, and the total production of corn becomes bushels per week.
