10. The most common species of sweat bees are green, red, and yellow. For each color, we select a sample of 100 of bees of this color and record their length (in inches). We then create 3 data sets of 100 observations each, called "green", "red" and "yellow". Below are the boxplots and histograms for these data sets. The labels of the variables are missing from the histograms, but are included in the boxplots. Our task is to identify the missing labels. Which one of the following statements is correct?

1. A researcher wishes to determine if the following distances (in meters) traveled by a random sample of ten world-class long jumpers are highly affected by the speed (in meters per second) at takeoff. The distances recorded from the sample long jumpers are as follows: 7.67, 8.22, 7.94, 7.16, 8.08, 7.35, 7.89, 7.76, 7.25, and 7.43. On the other hand, the speeds are recorded as follows: 8.9, 9.2, 8.1, 8.6, 9.0, 8.4, 8.8, 9.1, 8.0, and 8.2. What will be the distance, assuming that the speed is 9.4 meters per second? Round your answer to two decimal places. There is no need to place the unit. 2. A certain regression line equation has the slope equal to 720.25 and an intercept that is equal to -182.4.
