An ice cream shop at Bondi hires an American consultant to estimate a regression equation that
may be used to predict sales using the forecasted maximum daily temperature. The consultant
produces the following regression model: sales=20+10F,R2=0.4 where F is the forecasted
maximum daily temperature in Fahrenheit. Unfortunately, the shop needs a model that accepts
temperatures measured in Celsius. If the model was re-estimated using Celsius, what would be
the values of:
(a) the intercept?
(b) the slope term?
(c) the R2 ?
The formula for converting temperatures in Fahrenheit to Celsius is C=59(F32) In each case, your
answers should be accurate to 3 decimal places.
