Question

The average temperature in a certain city has a statistically significant correlation to the monthly precipitation, measured inches. The regression line ý = 0.15x + 11.08 models this relationship when the temperature is between 75 and 90 degrees. Use the line to predict the monthly precipitation if the temperature is 79 degrees. Round your answer to the nearest hundredth.

[AI-generated answer — Bot GPT 3.5]

To predict the monthly precipitation when the temperature is 79 degrees, we can plug in x = 79 into the regression line equation:

ŷ = 0.15(79) + 11.08
ŷ = 11.85 + 11.08
ŷ = 22.93

Therefore, the predicted monthly precipitation when the temperature is 79 degrees is 22.93 inches.
