Question

A grocery store is interested in how customers' income affects the amount of money
they spend each week. A regression analysis is performed to test this analysis. The
results of the analysis are that the intercept is $17.80 and the slope is 0.0012. Based
on these results, what is the predicted weekly grocery expenditure (to the nearest
cent) for a household with an income of $65,000?
$95.80
O$78.00
$45.23
$17.80
Ho: mean weekly expenditure = $78.00

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
