The regrossion equation is y = 37.5 (0.0419)x
(Round the y-intercept to one decimal place as needed, Round the slope to four decimal places as needed )
The best predicted temperature at a time when a cricket chirps 3000 times in 1 minute, based on the regression equation, is 163 2 F
(Round to the nearest integer as needed)
What is wrong with this predicted temperature?
O A. The chirps in 1 minute should have been the dependent variable:
OB. It is only an approximation. An unrounded value would be considered accurate.
O C. It is unrealistically high The value 3000 is far outside of the range of observed values.
O D. Nothing is wrong with this value It can be treated as an accurate prediction
