Question

Based on the scatterplot and computer output, a reasonable estimate for the home's electric bill when the mean monthly temperature is 76 degrees is:

1) 145.30 because ŷ = 1.9313(76) - 1.4806 = 145.308
2) 60 because and e2.1518 = 8.60
3) 141.85 because and 102.1518 = 141.85
4) 4,923.97 because and 103.6923 = 4923.97

Answer 1

A reasonable estimate for the home's electric bill when the mean monthly temperature is 76 degrees is $145.30.

Step-by-step explanation:

To estimate the home's electric bill when the mean monthly temperature is 76 degrees, we can use the given equation: y' = 1.9313x - 1.4806, where y' represents the electric bill and x represents the mean monthly temperature. Plugging in x = 76, we get y' = 1.9313(76) - 1.4806 = 145.308.

Therefore, a reasonable estimate for the home's electric bill when the mean monthly temperature is 76 degrees is $145.30.
