I need help with this question please. Thanks in advance.
The following chart shows estimated January retail inventories in the United States in 2000, 2005, and 2007 (t = 0 represents 2000):
| Year t | 0 | 5 | 7 |
| Inventory ($ billion) | 380 | 430 | 500 |
Find the regression line (round coefficients to two decimal
places).
y =
Use your regression equation to estimate January retail inventories
in 2004.
$ ______ billion
Homework Answers
We can use here Excel for regression equation
Step 1) Enter data in Excel .
Step 2) Data >>Data analysis >>Regression >>Select y and x values separately >>Ok
The regression line is
y=373.59+15.77*t
t=4 for year 2004
Substitute t=4 in regression equation
=> y=373.59+15.77*(4)
=436.67
i.e. $436.67 billion

1. Exercise 5.1 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 is: where k has been estimated (from past data) to equal 100 If Y $13,000, Z- $1,200, and P...
