Chapter 9.4, Problem 1JC
Recall the regression example in Chapter 7 to predict hurricane maximum wind speed from central barometric pressure. Another researcher, interested in the possibility that global warming was causing hurricanes to become stronger, added the variable Year as a predictor and obtained the following regression: (Data in Hurricanes 2015)
Dependent variable is: Max. Winds (kn)
R-squared = 80.6 s = 8.13
| Variable | Coefficient |
| Intercept | 1032.01 |
| Central Pressure | –0.975 |
| Year | –0.00031 |
1. Interpret the R2 of this regression.

- In a study of how students give directions, forty volunteers were given the task ofexplaining to another person how to reach a destination. Researchers measured thefollowing five aspects of the subjects’ direction-giving behavior:• whether a map was available or if directions were given from memory without a map,• the gender of the direction-giver,• the distances given as part of the directions,• the number of times directions such as “north” or “left” were used,• the frequency of errors in directions. Identify each of the variables in this study, and whether each is quantitative orqualitative. For each quantitative variable, state whether it is discrete or continuous. Was this an observational study or an experimental study?
