Use the following information for following questions .
Data were recorded for 117 months on a household's gas bill (in dollars) and the average monthly temperatures for its neighborhood. The mean monthly temperature was 48.7° F with a standard deviation of 20.6. The mean gas bill price was $81.20 with a standard deviation of 66.5. The correlation coefficient between monthly temperature and gas bill price is −0.92.
-Determine the correct value of the slope for the linear model that predicts gas bill price from monthly temperature and interpret it in context.

A) The slope is −2.97.For every one degree increase in monthly temperature, the gas bill price is predicted to decrease by $2.97.
B) The slope is −2.97.For every one dollar increase in gas bill price, the monthly temperature is predicted to decrease by 2.97°.
C) The slope is −0.28.For every one degree increase in monthly temperature, the gas bill price is predicted to decrease by $0.28.
D) The slope is −0.28.For every one dollar increase in gas bill price, the monthly temperature is predicted to decrease by 0.28°.
