AP Statistics Question Help:

The data below were gathered on a random sample of 5 basking sharks, swimming through the water and filter-feeding, i.e. letting the water bring food into their mouths.

Body Length (meters) Mean Speed (meters/seconds)
4 0.89
4.5 0.83
4 0.76
6.5 0.94
5.5 0.94

a) If these sharks are representative of the population of basking sharks, what would you predict is the mean speed for a filter-feeding basking shark that is 5.0 meters in length? Show any calculations below.

The Least Squares Regression Line

amistre64 · Answer

define the line in point slope form, using the average x and average y as the point, and the slope can be determined by the formula:$$m=\frac{n\sum xy-\sum x\sum y}{n\sum xx-\sum x\sum x}$$
