Question

Anand decides to research the relationship between the length in inches and theweight of a certain species of catfish. He measures the length and weight of a numberof specimens he catches, then throws back into the water. After plotting all his data,he draws a line of best fit. Based on the line of best fit, how much would you predict acatfish with a length of 33 inches would weigh?

Answer 1

From the best line fit we notice that for each inch the length increases the weight increases two units. Then, from the las point, if we increase the length two inches the weight will increase 4 pounds. Therefore the weight will be 33 punds.
