Textbook Question
Chapter 8, Problem 43E
TBill rates 2016 revisited In Exercise 41, you investigated the federal rate on 3-month Treasury bills between 1950 and 1980. The
Here’s the model for the data from 1981 to 2015 (in years since 1950):
Dependent variable is Rate
R-squared = 79.1% s = 1.584
Variable | Coefficient |
Intercept | 8.5922 |
Year – 1950 | –0.29646 |
- a) How does this model compare to the one in Exercise 41?
- b) What does this model estimate the interest rate will be in 2020? How does this compare to the rate you predicted in Exercise 41?
- c) Do you trust this newer predicted value? Explain.
- d) Would you use either of these models to predict the TBill rate in the future? Explain.

A researcher interested in explaining the level of foreign reserves for the country of Barbados estimated the following multiple regression model using yearly data spanning the period 2001 to 2016:
??=?+????+????+????
Where FR = yearly foreign reserves ($000’s), OIL = annual oil prices, EXP = yearly total exports ($000’s) and FDI = annual foreign direct investment ($000’s). The sample of data was processed using MINITAB and the following is an extract of the output obtained:

This might have occurred because when the pole vault was a new event there was much room for improvement in vaulters’ performances, whereas now even the best training can produce only incremental advances. Let’s see whether concentrating on more recent results gives a better predictor of future records. (a) Use the data in Table 2 (page 176) to complete the table of winning pole vault heights shown in the margin. (Note that we are using x=0 to correspond to the year 1972, where this restricted data set begins.) (b) Find the regression line for the data in part ‚(a). (c) Plot the data and the regression line on the same axes. Does the regression line seem to provide a good model for the data? (d) What does the regression line predict as the winning pole vault height for the 2012 Olympics? Compare this predicted value to the actual 2012 winning height of 5.97 m, as described on page 177. Has this new regression line provided a better prediction than the line in Example 2?arrow_forward
