Question

A solar power company is trying to correlate the total possible hours of daylight (simply the time from sunrise to sunset) on a given day to the production from solar panels on a residential unit. They created a scatter plot for one such unit over the span of five months. The scatter plot is shown below



(b) To the nearest tenth of an hour, how many hours of possible daylight would be needed to produce 50 kilowatt hours of energy?





(c) The correlation coefficient for this regression was . Would you characterize this as strongly positive, moderately positive, or a weakly positive correlation? Explain.




(d) Based on (c), do you have confidence in the model to accurately predict the energy production based on the total possible daylight hours? Explain.



(e) What environmental factors might contribute to the “noise” in the data? Noise are factors that prevent the correlation from being perfect.
