A linear regression analysis is run on this data and results in a linear regression
equation of y- 4.36x - 156.14 where x is the length of the shark in inches and y is
the weight of the sharks in pounds. The correlation coefficient Ir is calculated as
0.9991.
Interpret the slope of the regression line in context.
Each pound more a sand shark weighs adds exactly 4.36 inches to its length
On average. for every 1 inch longer a sand shark is, it will weight 4.36 more
pounds,
O Each inch longer a sand shark is adds exactly 4.36 pounds to its weight
O On average, for each pound heavier a sand shark is, it will be 436 inches longer.
