Analysis Of The Sales Portions Of The Stretch’r Wings

Unit 8 Assignment

Provide an analysis of the sales portions of the Stretch’r Wings (a hypothetical company) marketing plan at BPlans. Their sales approach is described in Sections 5 and 6 of the plan.

To find this sales approach:

Analysis Of The Sales Portions

- Click Browse free sample plans.
- Then click Aircraft Equipment Maker Business Planto find the Stretch’r Wings, Inc. marketing plan.
Consider the following:

- Describe the components of their sales approach.
- Discuss whether or not you think their sales plan is effective for a business in that market with that marketing mix.
- Discuss whether or not you think they have enough detail in their business plan to effectively communicate their sales plan.
Suggest additions and changes to their sales plan to make it more comprehensive and to better communicate the sales approach.

1.

Pearson Correlation cannot be used to identify non-linear relationships between two variables.

A) True

B) False

2.

Regression cannot be used to identify non-linear relationships between two variables.

A) True

B) False

3.

Suppose you have a regression model that depicts the relationship between sales in dollars (S) and theprice of the product in dollars (P) such that S = 10 – 2P. Which of the following is the correct

interpretation of the price coefficient (i.e., -2)?

A) A $1 increase in price will decrease sales by $2.

B) A $1 increase in sales will occur if there is a $2 decrease in price.

C) A 1% increase in price will cause a 2% decrease in sales.

D) A 1% increase in sales will be caused by a 2% decrease in price.

4.

Suppose you have a regression model that depicts the relationship between sales in dollars (S) and theprice of the product in dollars (P) such that log(S) = 10 – 2(logP). Which of the following is the correct

interpretation of the price coefficient (i.e., -2)?

A) A $1 increase in price will decrease sales by $2.

B) A $1 increase in sales will occur if there is a $2 decrease in price.

C) A 1% increase in price will decrease sales by 2%.

D) A 1% increase in sales will result from a 2% decrease in price. Situation 8.1:

A chemist employed by a pharmaceutical company has developed a muscle relaxant. She took a sample

of 14 people suffering from extreme muscle constriction. She gave each a vial of the liquid drug and

recorded the time to relief (measured in seconds)for each. She then estimated a regression model to this

data and found the following: Relief = 1283 (3.65) – 25.22Dose (2.92) – 0.86DoseSquared (2.13) where

numbers in parentheses are t-statistics for the corresponding variable coefficient. 5.

The chemist ask you to determine if the there is a significant relationship between dose and time to

relief. Using a one-tail test, your best answer would be:

A) Given the results provided, dose is significant at .01 level.

B) Given the results provided, dose is significant at the .05 level.

C) Given the results provided, dose is significant at the .10 level.

D) Given the results provided, dose does not significantly affect time to relief.

6.

Suppose the chemist decides to determine if there is a quadratic effect (e.g. DoseSquared). Should thechemist use a one-tail or two-tail test?

A) A one-tail since the effect of increasing the dosage will eventually taper off so expect dose squared to

be negative.

B) A one-tail test since the effect of increasing the dosage will be to accelerate time to relief so expect

sign of dose squared is positive.

C) A two-tail test since we do not know what effect an increased dosage will have so do not know sign to

expect for dose squared.

D) One could select either a one-tail or two-tail test as long as test at alpha = 0.01.

7.

The chemist concludes that there is a quadratic effect (Dose-squared) for the muscle relaxation

medication. This conclusion is appropriate using a two-tail test and alpha = .05.

A) True

B) False 8.

A dummy variable is used when:

A) Two variables are collinear.

B) The model is non-linear

C) The variable is categorical or qualitative.

D) The preferred variable is missing and you must use a proxy variable. You are hired by a major refrigerator manufacturer to estimate the demand for their refrigerators. You use thefollowing independent variables in this effort. i. Population (POP), age 21-35, in thousands. ii. Housing starts (H), in thousands.

iii. Refrigerator price index (P).iv. Disposable personal income per capita (Y), in thousands of dollars.

v. Advertising expenditures (A), in thousands of dollars.

Replacement trend (R), a replacement probability function

vi. constructed from prior refrigerator sales, based on a 16-year average

refrigerator life, and average age of refrigerators in market area.

Quarterly data for the years 1997 through 2002 were used to run the regression on refrigerator sales (in

thousands). The results are described in Tables 1 and 2 below.

Assuming that a one-tail test is appropriate for all coefficients and a significance level of .05, which of the

variables in the model are significant (exclude constant or intercept from consideration)?

A) R,H,A

B) R,H,A,P

C) R,H,A,P,Y

D) R,H,A,P,Y,POP

10.

What problem can be caused by multicollinearity?A) The inability to isolate the distinct effects of the related independent variables.

B) Smaller than expected p-values leading to misinterpretations.

C) Smaller than expected standard errors leading to wrong conclusions.

D) Significant t-values and a high R-squared. 11.

Which of the following is the best example of the potential issues associated with multicollineary?

A) Adjusted R-squared is less than R-squared.

B) H and R have a low correlation but both have significant coefficients.

C) POP and Y are correlated and both have insignificant coefficients.

12.

Suppose you check on seasonality in the sales of refrigerators by creating the following variables: Q1 = 1if first quarter, 0 otherwise; Q2 = 1 if second quarter, 0 otherwise; and Q3 = 1 if third quarter, 0

otherwise. The coefficient for Q2 equals +0.5 and is statistically significant and Q4 is the “omitted”

category. Interpret Q2.

A) There are, on average, 500 more refrigerators sold in the second quarter, holding constant the other

variables.

B) There are, on average, 500 more refrigerators sold in the second quarter than the first quarter, holding

constant the other variables.

C) There are, on average, 500 more refrigerators sold in the second quarter than the third quarter,

holding constant the other variables.

D) There are, on average, 500 more refrigerators sold in the second quarter than the fourth quarter,

holding constant the other variables.
