Chapter 5, Problem 1E
The
where k has been estimated (with past data) to equal 100.
- If
- What happens if P is reduced to $17,500?
- How would you go about developing a value for k?
- What are the potential weaknesses of this model?
a)
Expert Solution
To determine
To calculate: The value of S (sales).
Answer to Problem 1E
The value of S is $66000
Explanation of Solution
S = Sales
Y = Disposable personal income
Z = population between the age group
P = inverse price
K = estimated data
b)
Expert Solution
To determine
To ascertain: The effect of decrease in the value of P.
Answer to Problem 1E
The sales will increase by 75429 − 66000 = $9429
Explanation of Solution
The sales will increase by 75429 − 66000 = $9429
c)
Expert Solution
To determine
To find: The process to develop the value for K.
Explanation of Solution
The past data of S, Y, Z and P is required where,
S = Sales
Y = Disposable personal income
Z = population between the age group
P = inverse price
K = estimated data
to formulate the value of k. However, this data will be utilized by various techniques like regression analysis in order to find the value of k.
d)
Expert Solution
To determine
To detect: The potential weakness of the model is to be determined.
Explanation of Solution
The given model depends on three constituents, Y, Z, and P. Therefore, any change in these consequents will change the value of sales. Moreover, it will be difficult to find the consequent that is responsible to change in sales(S).

The 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.

You have collected data for the 50 U.S. states and estimated the following relationship between the change in the unemployment rate from the previous year (Aur) and the growth rate of the respective state real GDP (gy). The results are as
follows:
R² = 0.36, SER=0.78
Aur=2.81-0.23xgy
(0.12) (0.04)
Assuming that the estimator has a normal distribution, the 95% confidence interval for the slope is approximately the interval:
OA. [2.57, 3.05].
OB. [-0.31, 0.15].
OC. [-0.31, -0.15].
OD. [-0.33, -0.13].

- Which one of the following statements is true for a linear regression model with non-spherical disturbances (i.e. E(uu') = Ω): The GLS estimator covariance matrix is unreasonable. The OLS estimator is not consistent. The standard formula for the OLS estimator covariance matrix is incorrect. The GLS estimator is not consistent. All of the above. None of the above.arrow_forwardAll questions utilize the multivariate demand function for Smooth Sailing sailboats in C6 on text page 83. Compute to three decimal places. Initial values are: PX = $9500 PY = $10000 I = $15000 A = $170000 W = 160 This function is: Qs = 89830 -40PS +20PX +15PY +2I +.001A +10W 1.(a). Use the above to calculate the arc price elasticity of demand between PS = $9000 decreasing to PS = $8000. The arc elasticity formula is: 1.(b). Judging from the computation in (a), do you expect the revenue resulting from the decrease in Ps to $8000 to increase, remain the same, or decrease relative to the revenue at Ps = $9000. (Hint: see the table on page 65 of Truett). Explain your choice. 1.(c). Calculate the point elasticity of demand for Smooth Sailing sailboats at PS = $9000 (which should make Qs = 101600). The formula is: 1.(d). Does this elasticity value indicate that Smooth Sailing demand is relatively responsive to changes in the price of these sailboats? Explain…arrow_forwardThe measure of standard error can also be applied to the parameter estimates resulting from linear regressions. For example, consider the following linear regression equation that describes the relationship between education and wage: WAGEi=β0+β1EDUCi+εi where WAGEi is the hourly wage of person i (i.e., any specific person) and EDUCiEDUCi is the number of years of education for that same person. The residual εiεi encompasses other factors that influence wage, and is assumed to be uncorrelated with education and have a mean of zero. Suppose that after collecting a cross-sectional data set, you run an OLS regression to obtain the following parameter estimates: WAGEi=−12.3+4.4 EDUCi If the standard error of the estimate of β1 is 1.29, then the true value of β1 lies between (2.465, 3.11, 3.755, 1.82) and (5.69, 6.98, 5.045) . As the number of observations in a data set grows, you would expect this range to (INCREASE OR DECREASE) in size.arrow_forward
