Answer to Question 1

There appears to be a moderately strong, positive, but nonlinear (curved) association between speed and number of strikeouts. Pitchers with higher speeds tend to have more strikeouts. There is one point that doesn't fit the pattern. One pitcher had more strikeouts on average than his average speed would typically indicate.

Answer to Question 2

The points in the bottom left corner seem to have extremely low calorie content for cereals between zero and six grams of fiber. The points with 9, 10 and 14 grams of fiber appear to have an unusually high amount of fiber for their calorie content, making them outliers and influential points. These three points would also be leverage points, creating the impression that there is a negative association between grams of fiber and the number of calories in the cereals.
