Pretzels In order to judge the effectiveness of an advertising campaign for a certain brand of pretzel, a company obtained a simple random sample of convenience store receipts the week before the ad campaign began, and found that of them showed a purchase of the pretzels. Another simple random sample of receipts was taken the week after the ad campaign, and of them showed a pretzel purchase. Required:
a. Construct a 98% confidence interval for the difference between the proportions of customers purchasing pretzels before and after the ad campaign.
b. A marketing manager claims that the proportion of customers who purchased pretzels did not change after the ad campaign. Does the confidence interval contradict this claim?

Ok, so, theoretical question: if i bought the mona lisa legally, would anyone be able to stop me from eating it? why or why not?

Need with my trade theory homework. i doubt what i wrote was right. consider a monopolistically competitive market for soft drinks in which n symmetric firms face the following demand function: q=s(1/n-b(p-(p with the straight line on which implies the marginal revenue functionmr=p-(q/sb)finally, suppose firms face the total cost functiontc=900,000+100qsuppose the market size, s, is 27,000,000, and the elasticity parameter b is 0.003.diagram the price and the average total cost in the market as a function of the number of firms. what are the equations for each curve, and why does each curve slope up or down? label the equilibrium number of firms and the equilibrium price in the diagram. why is this the equilibrium?

Suppose the following items were taken from the balance sheet of nike, inc. (all dollars are in millions.) 1. cash $ 2,316.7 7. inventory $ 2,245.6 2. accounts receivable 2,786.2 8. income taxes payable 80.3 3. common stock 2,841.1 9. equipment 1,783.8 4. notes payable 291.2 10. retained earnings 6,162.5 5. buildings 3,959.7 11. accounts payable 2,624.6 6. mortgage payable 1,092.3 perform each of the following. classify each of these items as an asset, liability, or stockholders’ equity, and determine the total dollar amount for each classification. (enter amounts in millions up to 1 decimal place, e. g. 45.5 million.) cash accounts receivable common stock notes payable buildings mortgage payable inventory income taxes payable equipment retained earnings accounts payable assets $ 13092 liability $ 4088.4 stockholders’ equity $ 9003.6 etextbook and media determine nike’s accounting equation by calculating the value of total assets, total liabilities, and total stockholders’ equity. (enter amounts in millions up to 1 decimal place, e. g. 45.5 million.) total assets = total liabilities + total stockholders’ equity
