An energy company wants to choose between two regions in a state to install​ energy-producing wind turbines. A researcher claims that the wind speed in Region A is less than the wind speed in Region B. To test the​ regions, the average wind speed is calculated for 90 days in each region. The mean wind speed in Region A is 13.8 miles per hour. Assume the population standard deviation is 2.8 miles per hour. The mean wind speed in Region B is 15.1 miles per hour. Assume the population standard deviation is 3.2 miles per hour. At alpha0.05​, can the company support the​ researcher's claim? Complete parts​ (a) through​ (d) below.

Assuming an initial forecast for week 1 of 17,000 miles, use exponential smoothing to

compute miles for weeks 2 through 12. Use α = 0.2.

What is the MAD for this model?

Compute the RSFE and tracking signals. Are they within acceptable limits?

PLEASE ANSWER THE RSFE question Thank you

You have been hired by a used-car dealership to modify the price of cars that are up for sale. You will get the information about a car, and then change its price tag depending on a number of factors. Write a program (a script named: 'used_cars.m' and a function named 'car_adjust.m').The script passes the file name 'cars.dat' to the function. The following information is stored inside the file:

Ford, 2010 with 40,000 miles and no accident at marked price of $6500

Lexus, 2011 with 100,000 miles and 1 accident at marked price of $40,000

Toyota, 2008 with 20,000 miles and 2 accidents at marked price of $14,000

Audi, 2012 with 10,000 miles and no accident at marked price of $45,000

The function will open the file and store its content and creates a structure with the following fields:

Make: A string that represents the make of the car (e.g. ‘Toyota’)

Year: A number that corresponds to the year of the car (e.g. 2000)

Cost: A number that holds the cost of the car (e.g. 8000)

Price: A number that holds the marked price of the car Miles:

The number of miles clocked (e.g. 85000) Accidents:

The number of accidents the car has been in. (e.g. 1)

Your function will then return the structure to the script with all the above fields, with exactly the same names. Here is how you must calculate the Cost of each car: 1. Add 4000 to the cost if the car has clocked less than 30000 miles. 2. Subtract 2000 if it has clocked more than 90000 miles. 3. Reduce the price by 1000 for every accident. From inside your script, call different elements of the structure and make sure it returns the correct values.

Offer suggestions on how revenue management can be used to actually enhance guest loyalty in the hotel and/or travel industry

Scenario: A local park is being converted into a COVID-19 testing site.

Describe the internal and external stakeholders, and their importance.

The Hotel has two operating departments. Rooms and F&B. 70% of the hotel's total revenue is earned from room sales and 30% of the total revenue is earned from F&B sales.

Rooms department's contribution margin ratio is 60% and F&B department's contribution margin ratio is 50%. If the fixed cost of the hotel is $400,000, and the management is targeting a before -tax profit of $150,000, what is the required sales revenue? (Rounded to whole numbers)

A.$964,912

B.$795,230

C.$1,234,502

D.$701,754
