Construct an estimated regression line between temperature and number of units
sold.
а)
b)
Does the model in part (a) confirm that contribution of temperature to number of
units of air conditioner sold? Test using a 0.05.
Find the coefficient of correlation. What does the value imply about the relationship
of the two variables?
c)
If the temperature soared to 120 Fahrenheit, can you predict the number of units of
air conditioner sold? Explain
d)
