A regression study of the relationship between the boiling temperature of water (y,in degrees Fahrenheit) and the atmospheric pressure (x, in inches of mercury) based on a data set withn= 30 observations resulted in the following regression equation:ˆy= 149 + 2.1x. If the average of the 30 atmospheric pressure reading (i.e. ̄x)was 20 inches of mercury, then what the average of the boiling temperature reading(i.e. ̄y) for these 30 observations.
