Orion is working with a data set that compares the outside temperature, in degrees celsius, to the number of gallons of ice cream sold per day at a local grocery store.
the data has a line of best fit modeled by the function f(x) = 3x + 4 . orion determines that when the temperature is 25∘c, the store should sell about 79 gallons of ice cream. the correlation coefficient of the data is 0.39.
explain how accurate orion expects the prediction to be.
