Concept explainers
A company manager wants to establish a relationship between the sales of a certain product and the price. The company research department provides the following data:
(a) Use a calculating utility to find the regression line of y as a function of x.
(b) Use a graphing utility to make a graph that shows the data points and the regression line.
(c) Use the regression line to make a conjecture about the number of units that would be sold at a price of

- Find the equation of the regression line for the following data set. x 1 2 3 y 0 3 4arrow_forwardDemand 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 2.00arrow_forward
