Question
12. Demand for Candy Bars In this problem you will determine a linear demand equation that
describes the demand for candy bars in your class. Survey your classmates to determine what
price they would be willing to pay for a candy bar. Your survey form might look like the sample
to below.
Would you buy a candy bar from the vending machine in the hallway if the price is as indicated?
Price
Yes or No
50c
75c
$1.00
$1.25
$1.50
$1.75
$2.00
(a) Make a table of the number of respondents who answered "yes" at each price level.
(b) Make a scatter plot of your data.
(c) Find and graph the regression line y = mp+b, which gives the number of respondents y
who would buy a candy bar if the price were p cents. This is the demand equation. Why is
the slope m negative?
(d) What is the p-intercept of the demand equation? What does this intercept tell you about
pricing candy bars?
