a. The following readings were taken from a display outside the First River Bank. The display alternated between °F and °C. However, there was an error within the system that calculated the temperatures.

b. Calculate the residuals. You will notice that the residuals are generally negative for the lower temperatures and positive for the higher temperatures. How is this represented on the graph of the data and line?
c. Adjust your equation (by adjusting the slope or y-intercept) to improve this distribution of the residuals.
d. Calculate the root mean square error for the median-median line and for the equation you found in 8c. Compare the root mean square errors for the two lines and explain what this tells you.
e. Use your equation from 8c to predict what temperature will be paired with i. 85°F, ii. 0°C
