Shegathers data for apartment buildings in 12 cities in 12 different states. In each city, she gets thenumbers for at least 5 different buildings and at least 40 apartments in each building. She reaches thefollowing conclusion: the rental cost of a 2-bedroom apartment is 50% more than the rental cost of a1-bedroom apartment, and the rental cost of a 3-bedroom apartment is 50% more than the rentalcost of a 2-bedroom apartment.Based on the paragraph, what is the minimum number of apartments she collected data on?Do you think her sample was large enough to be statistically valid?Based on the paragraph, are there any apartments or apartment buildings that she would have excludedfrom her study?Do you see any bias in how she selected apartments for her study?Based on the paragraph, is there a positive correlation, a negative correlation, or no correlationbetween the number of bedrooms and the monthly rent?If her conclusion is valid, and you are renting a 1-bedroom apartment for $800 per month, how muchrent would you expect to pay if you moved to a 3-bedroom apartment nearby?

. In 2010, of a total of 67,000 rooms on the Las Vegas Strip, Caesars Entertainment managed 22,880, while MGM Resorts managed over 12,000. However, owing to the Great Recession and new hotel openings, between 2008 and 2010, MGM's hotel occupancy decreased from 92% to 89%, while its average daily room rate fell from $148 to $108. Meanwhile, CityCenter, managed by MGM Resorts, and the Cosmopolitan opened with 4,000 and 3,000 rooms respectively, and the 1,720-room Sahara closed. (Sources: Caesars Entertainment Corp., Annual Report 2010; MGM Resorts, Annual Report 2010; "Sahara's closure on May 16 will mark `the end of an era'," Las Vegas Sun, March 11, 2011.) (a) Using a suitable figure, explain how the opening of CityCenter and the Cosmopolitan affects the residual demand for an existing hotel and how it should adjust prices. (b) If MGM Resorts had not reduced its room rates, what would have been the effect on occupancy? (c) Use the Cournot model to explain…

2. Write a program that models a cashier at a store. The program will take two numbers as input. Firstly, the cost of an item ($20.00 or less). Secondly, the amount of money given to the cashier ($20.00 or less). The program should output the change given in 10 dollar bills, 5 dollar bills, 1 dollar bills, quarters, dimes, nickels, or pennies. You should output the highest denominations possible. For example, if the item costs $5.20 and the cashier is given $10 then the change should be 4 dollar bills 3 quarters 1 nickle
In 1993 the average expenditure of the employees on food and other items was as follows : In Cuttack In Bhubaneswar (i) Food 60% (ii) Other items 40% 50% 50% In 1998, the cost of living index was 279 for Cuttack and 265 for Bhubaneswar with 1993 as the base. The rise in price of all the items used by the employeees was known to be the same for both the towns. Determine the 1998 index for (i) food and (ii) other items.
