You’ve been hired as a consultant for a new planned NYC “quadrathalon”, in which participants run from Hunter’s Point South Park in Queens to Socrates Sculpture garden, take a kayak from there to Roosevelt Island, swim from there to John Jay park on Manhattan, cycle across to the Boat Basin, then swim down to a concluding party at Riverside pier 1. The organizers are worried about pollution while swimming in the two rivers. Studies have show the East River has unacceptable pollution levels a percentage of time given by p_E in the data sheet, while the Hudson river has unacceptable levels p_H of the time. Assuming these probabilities are independent answer the following:
p_E = 52 p_H = 22 p_HE = 37
You have received new information: if the East River is contaminated, the chances of the Hudson river also being contaminated goes up to p_HE (Manhattan pollutes both). Redo the questions above using this new information.

-What is the probability of having only one river contaminated? (they can move the kayak section from one river to the other).
-What is the probability of having neither river contaminated?

A singer quartet consisting of Angel, Betty, Carlos and Diana wants to practice their singing. However due to the pandemic they decide to do so at a baseball park to keep social distancing. Angel stands on the home plate, Betty goes to third base, Carlos to second base and Diana to first base. While they are getting ready a bird flies along the line joining third base and home, Betty says “That bird is singing at a frequency of 350 hertz”, but Angel says “No, it is singing at 340 hertz.” Soon after the bird leaves the park Diana sings a 440 hertz note, Carlos hears it 0.1 second later and sings a 261 hertz note.
Part a
Make a drawing of the bird’s flight path along the line joining third base and home, with an arrow indicating the direction of flight, towards home or away from home.
Part b
Explain why you chose that direction, include any equations that support your explanation.
Part c
How far is Carlos from Diana? Show your calculations.
Part d
What is the period of Carlos’ note at 261 Hertz. Include your calculations

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use . Factor A is method of loading and unloading; Factor B is the type of ride.
| Type of Ride | |||
| Roller Coaster | Screaming Demon | Long Flume | |
| Method 1 | 48 | 53 | 51 |
| 50 | 45 | 47 | |
| Method 2 | 47 | 54 | 51 |
| 49 | 50 | 47 | |
Set up the ANOVA table (to whole number, but -value to 2 decimals and value to 1 decimal, if necessary). The p-value for Factor A is? What is your conclusion with respect to Factor A? The p-value for Factor B is? What is your conclusion with respect to Factor B? The p-value for the interaction of factors A and B is? What is your conclusion with respect to the interaction of Factors A and B? What is your recommendation to the amusement park?

The lease of Theme Park, Inc., is about to expire. Management
must decide whether to renew the lease for another 10 years or to
relocate near the site of a proposed motel. The town planning board
is currently debating the merits of granting approval to the motel.
A consultant has estimated the net present value of Theme Park’s
two alternatives under each state of nature as shown below. Suppose
that the management of Theme Park, Inc., has decided that there is
a 0.21 probability that the motel’s application will be
approved.
| Options | Motel Approved |
Motel Rejected |
||
| Renew | $ | 410,000 | $ | 4,025,000 |
| Relocate | 2,025,000 | 110,000 | ||
a-1.
If management uses maximum expected monetary value as the decision
criterion, calculate expected monetary value for the alternatives
"Renew" and "Relocate"? (Omit the "$" sign in your
response.)
| Alternative | Expected Value |
| Renew | $ ?? |
| Relocate | $ ?? |
a-2. Which alternative should it choose?
Renew lease??
Relocate??
c. If management has been offered the option of a
temporary lease while the town planning board considers the motel’s
application, would you advise management to sign the lease? The
lease will cost $21,000. (Omit the "$" sign in your
response.)
Yes because the cost is less than EVPI of $

HAS TO BE SOLVED IN EXCEL
Exercise 5A–1 High-Low Method LO5–11 NEEDS to be solved and shown in excel The Cheyenne Hotel in Big Sky, Montana, has accumulated records of the total electrical costs of the hotel and the number of occupancy-days over the last year. An occupancy-day represents a room rented for one day. The hotel’s business is highly seasonal, with peaks occurring during the ski season and in the summer. Month Occupancy-Days Electrical Costs January 1,736 $ 4,127 February 1,904 $4,207 March 2,356 $5,083 April 960 $2,857 May 360 $ 1,871 June 744 $2,696 July 2,108 $4,670 August 2,406 $ 5,148 September 840 $ 2,691 October 124 $ 1,588 November 720 $2,454 December 1,364 $3,529 Required: Using the high-low method, estimate the fixed cost of electricity per month and the variable cost of electricity per occupancy-day. Round off the fixed cost to the nearest whole dollar and the variable cost to the nearest whole cent. What other factors in addition to occupancy-days are likely to affect the variation in electrical costs from month to month

You are a database designer and data analyst working for the hypothetical employer, Park University. The University over the last few years has provided faculty and staff needed technology to support various job functions but is having some trouble tracking such technology to ensure the program is cost-effective. In other words, the University Controls Department is having difficulty locating inventories and associated invoicing information. With the lack of this important information, the University Controls department has a very difficult time locating and tracking released technology which has the intended purpose of being an asset to assigned employees and departments.
The University Controls department has a Technology Asset Management System currently designed and implemented using Microsoft Access; however, the Chief Information Officer (CIO) of Park University needs some ideas of possible reasons the current Technology Asset Management System designed in Microsoft Access is not currently tracking technology assets as intended.
In a memo style response to the Chief Information Officer (CIO), share-based on your knowledge learned about databases using experience and research, some possible and or hypothetical reasons why the existing database, in this case, is not working as intended?
