Problem 3: For each of the following plots, interpret the y-intercept of the least-squares egression line if possible. If not possible, explain why not. The least-squares regression line is y = 1.98 + 0.039x, where x is the temperature in a freezer in degrees Fahrenheit, and y is the time it takes to freeze a certain amount of water into ice. 3.5 3.0 Time to Freeze (hours) 0 -40 -30 -20 -10 0 10 20 30 40 Temperature ('Fahrenheit)
