Question
Out company supplies the bags of "party ice" cubes sold at all the convenience stores in Southern MD. We would like to develop an equation that will allow us to predict today's sales from the outside temperature, measured at 7: 00 AM. Here is the data from a few randomly chosen days: a. Write the equation of the line that will allow us to predict sales from the temperature. b. Predict the sales when the temperature is 80 degrees. c. Predict the sales when the temperature is -95 degrees. d. Predict the temperature when the sales of bags is 25.0 e. Predict the temperature when there are no sales of bags.Explanation / Answer
using minitab
Regression Analysis: temperature versus sales
The regression equation is
temperature = 19.35 + 1.299 sales
Regression Analysis: sales versus temperature
a)The regression equation is
sales = - 8.300 + 0.6600 temperature
b)sales = - 8.300 + 0.6600 temperature
temperature=80
sales = -8.30+0.6600*80
=44.50
c)
sales = - 8.300 + 0.6600 temperature
temperature= -95
sales = - 8.300 + 0.6600*(-95)
=-71
d) temperature = 19.35 + 1.299 sales
sales =25
temperature = 19.35 + 1.299 *25
=51.825
e)temperature = 19.35 + 1.299 sales
no sales of bag
sales=0
temperature = 19.35 + 1.299*0
=19.35
