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 the left. 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? Would you buy a candy bar from the vending machine in the hallway if the price is as indicated. Price Yes or No 50 75 1.00 1.25 1.50 1.75 2.00
S of 14 The relationship between x = height of a student (in inches) and y = number of steps required to walk the length of a school hallway, is summarized with the regression line ŷ = 113.6 - 0.921x. For this model, technology gives s = 3.50 and = 0.399 . Interpret the value of s. O The actual number of strides required to walk the length of a school hallway is typically about 3.50 less than the number predicted by the least-squares regression line with x= height of a student (in inches). O The number predicted by the least-squares regression line is typically about 3.50 away from the actual number of strides required to walk the length of a school hallway with x height of a student (in inches).
