Question

Nathan 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. What is the meaning of the x-value on the line wheny = 44?* The expected weight of a catfish that is 44 inches long* Nathan caught a catfish that weighed 44 pounds* Nathan caught a catfish 44 inches long* The expected length of a catfish that weighs 44 pounds

Answer 1

Since the line of best fit represents the best linear model given the data, we can see that if y = 44 (pounds), then we are looking at the expected length of a catfish that weighs 44 pounds.
