D Question 1 3.5 pts Jasmin is concerned about how much energy she uses to heat her home, so she keeps a record of the natural gas her furnace consumes for each month from October to May. Because the months are not equally long, she divides each month's consumption by the number of days in the month. She wants to see if there is a relationship between x = average temperature (in degrees Fahrenheit) and y = average gas consumption (in cubic feet per day) for each month. Here is a scatterplot along with the regression line: y = 1425 - 19.87x. 1000 900 - 800 - 700- Average gas consumption (ft3 / day) 600 - 500- 400- 300 - 200- 25 30 35 40 45 50 55 60 Average temperature (F) Interpret the slope of the regression line: The [ Select ] v decreases by [ Select ] cubic feet per day for each increase of 1"F in the average monthly temperature. Does the value of the y intercept have meaning in this context? The y-intercept [ Select ] have meaning because it is [ Select ] to have a monthly average temperature of OF. If a month has an average temperature of OF, the [ Select ] is 1425 cubic feet per day. However, because this prediction is an | [ Select ) v, it may not be very accurate.
