- A model is built to explain the evolution of spending on tourism and recreation in a certain group of families (Y in USD/person/year). As potential explanatory variables are considered: X1 average annual income per person in the family (in USD), X2 – number of people in the family, X3 – nature of employment of the head of household If X3=1, when the head of the family is self-employed, X3=0, when the head of the family is an employee Based on the collected data, linear correlation coefficients between variables were calculated and obtained 0,84 R, = -0,47 [1 -0,55 0, 62 R= 1 -0,42 0,75 1 Using Hellwig's method, select the optimal combination of explanatory variables for the tourism and recreation expenditure model.Homework #8 Having the ability to monitor a process is critical in maintaining quality but also managing staff morale and/or fatigue. Please use the information below to answer the questions. Warehouse 36 produces birdhouses for Company X. Due to an illness that swept through the factory, Warehouse 36 is behind in production. In order to "catch up" to their predicted quota, the supervisor plans to work 12 hour shifts for 21 days. Over the course of the three-week period, production was steady and then began to decrease resulting in not meeting the goal of 340 units per day. Based on the information provided below, when did production begin to fall? At what point could a day off have prevented a production decrease? How do you know? Provide a visual display of data that shows the average, upper/lower class limits and daily production. (Hint - statistical process control) How could you have adjusted the schedule to reach the desired result?

It costs the hotel $30 per room in variable costs (cleaning, bathroom items, etc.) each night a room is occupied. For each reservation accepted, there is a 5% chance that the guest will not arrive. If the hotel overbooks, it costs $200 to compensate guests whose reservations cannot be honored. How many reservations should the hotel accept if it wants to maximize the average daily profit?
- The Jersey Dairy Products Company produces cheese, which it sells to supermarkets and foodprocessing companies. Because of concerns about cholesterol and fat in cheese, the company has seen demand for its products decline during the past decade. It is now considering introducing some alternative low-fat dairy products and wants to determine how much available plant capacity it will have next year. The company has developed an exponential smoothing forecast with a = .40 to forecast cheese demand. The actual demand and the forecasts from the model are as follows:Assess the accuracy of the forecast model by using MAD and cumulative error. If the exponential smoothing forecast model does not appear to be accurate, determine whether a linear trend model would provide a more accurate forecast.cipate worth S Exercise 2.9.8.
