The dataset shows 15 observations of the relationship between
cricket chirps (measured in chirps per second) and outside ground
temperature (in Fahrenheit).
A. Create a scatterplot by putting chirps on the vertical axis
and temperature on the horizontal axis. Be sure to properly label
the scatterplot with a title, axes titles, and the proper units of
the variables.
B. Estimate the following relationship:
