The current values of the independent variables are Ax=120, Px=0.95, and Py=0.64.Show all of your calculations and processes. Describe your answer for each question in complete sentences, whenever it is necessary. Calculate the price elasticity of demand for Newton’s Donuts and describe what it means. Describe your answer and show your calculations. Derive an expression for the inverse demand curve for Newton’s Donuts. Describe your answer and show your calculations. If the cost of producing Newton’s Donuts is constant at $0.15 per donut, should they reduce the price and thereafter, sell more donuts (assuming profit maximization is the company’s goal)? Should Newton’s Donuts spend…TRUE OR FALSE. A model with heterosdasticity problem most likely has insignificant parameter estimates.The demand function for a product is given by P = 4000/ln (x+10), where P is the price per unit in dollars when x units are demanded.i.

Find the rate of change of price with respect to the number of units sold when 90 units are sold.iii.

- If a Winters' model for new car dealer sales, comes up with four seasonal indices with values of Q1 = 0.95, Q2 = 1.04, Q3 = 1.05, and Q4 = 0.96, the following can be interpreted: Multiple Choice Q1 sales are lower because of Q2 sales.

Explain..In general, what is true about the relationship between the Sum of Squared Residuals in the restricted and unrestricted model? a. SSRr = R-squared * SSRur b. SSRr < SSRur c. SSRr > SSRur d. SSRr = SSRurThe forecasting staff for the Prizer Corporation has developed a model to predict sales of its air-cushioned-ride snowmobiles. The model specifies that sales S vary jointly with disposable personal income Y and the population between ages 15 and 40, Z, and inversely with the price of the snowmobiles P. Based on past data, the best estimate of this relationship isS = k (YZ/ P)where k has been estimated (with past data) to equal 100.a. If Y = $11,000, Z = $1,200, and P = $20,000, what value would you predict for S?b. What happens if P is reduced to $17,500?c. How would you go about developing a value for k?d. What are the potential weaknesses of this model?
- Eastman Publishing Company is considering publishing an electronic textbook about spreadsheet applications for business. The fixed cost of manuscript preparation, textbook design, and web site construction is estimated to be $172,000. Variable processing costs are estimated to be $5 per book. The publisher plans to sell single-user access to the book for $42. Through a series of web-based experiments, Eastman has created a predictive model that estimates demand as a function of price. The predictive model is demand = 4,000 − 6p, where p is the price of the e-book. (a) Construct an appropriate spreadsheet model for calculating the profit/loss at a given single-user access price taking into account the above demand function. What is the profit estimated by your model for the given costs and single user access price (in dollars). $ (b) Use Goal Seek to calculate the price (in dollars) that results in breakeven.
