Rainbow trout from the Spokane River in Washington State were measured. The length of the fish, L, is measured in millimeters (mm). The weight of the fish, W, is measured in grams (9). An expon 1600 1400 1200 1000 Weight (8) 800 600 400 200 100 200 300 400 500 Length (mm) This example is somewhat unique compared to the other problems we have worked in class because it uses length as the independent variable rather than time. Part 1 The equation of the trend line is W = 30.95(1+0.00763) What is the initial value of the trend line's equation? Include units. ---Select--- What is the interpretation of the initial value? State whether or not the interpretation is practical. O A fish's weight is expected to increase by 0.00763 grams per millimeter. This is a practical interpretation. O A fish's weight is expected to increase by 0.763% per millimeter. This is a practical interpretation. O A fish that is 30.95 millimeters long has an estimated weight of 0 grams. This number is needed in the formula, but it does not have a practical interpretation because all fish weigh more than 0 grams. A 0 millimeter fish has an estimated weight of 30.95 grams. This number is needed in the formula, but it does not have a practical interpretation because a 0 millimeter fish does not exist. The equation of the trend line is W = 30.95(1+0.00763)4 What is the growth rate of the trend line's equation? Express the growth rate as a percentage. Include units. ---Select--- What is the interpretation of the growth rate? State whether or not the interpretation is practical. A 0 millimeter fish has an estimated weight of 30.95 grams. This number is needed in the formula, but it does not have a practical interpretation because a 0 millimeter fish does not exist. O A fish's weight is expected to increase by 0.00763 grams per millimeter. This is a practical interpretation. O A fish's weight is expected to increase by 0.763% per millimeter. This is a practical interpretation. A fish that is 30.95 millimeters long has an estimated weight of 0 grams.
