Question:

In the following data, X is the Fahrenheit temperature and Y is the number of times a cricket chirps in 1 minute (see Problem 7, Section 4.1). Make a scatterplot of the data and discuss the appropriateness of using an 18th-degree polynomial that passes through the data points as an empirical model. If you have a computer available, fit a polynomial to the data and plot the results.

Data from problem 7

In Table 4.8, X is the Fahrenheit temperature, and Y is the number of times a cricket chirp in 1 minute. Fit a model to these data. Analyze how well it fits.
