Answer to Question 1

70 mph is lower than any of the speeds in these data, and extrapolation is risky business. Also, these data are for only pitchers on the Bulldogs, and may not be representative of others.

Answer to Question 2

The association would probably be weaker. This plot uses averages from an entire season. Data from a single month would have more variability.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
