A grocery store collects data on customer wait time in check out lines. If they want to know how much customer wait time falls each time they open up a new check out lane, what measure of association would be best? Regression Percentage change Correlation Standard deviation

Step 1
The question asks for the best measure of association to determine "how much customer wait time falls each time they open up a new check out lane." This implies a relationship where one variable (number of check-out lanes) influences another variable (customer Show more…

A department store manager explored the relationship between the percent of customers that wait more than 7 minutes in line and the percent of customers that purchase last minute items at checkout. The manager collects information from 5 checkout lines, shown in the table below. Use the graph below to plot the points and develop a linear relationship between the percent of waiting customers and the percent of last minute purchases. Line % of Waiting Customers % of Last Minute Purchases 1 25 3 2 35 11 3 50 16 4 60 20 5 70 30

One of the store managers regularly likes to keep 2 tills open on Saturdays. Use the equation of the regression line to provide the manager with the predicted time to check out if 2 tills are open. Which of the following cannot be answered from the regression equation? Clearly circle only one response. A prediction of the value of y at a particular value of x. An estimate of the slope between two variables. An estimate of whether the linear association between variables is positive or negative. An estimate of whether the association between variables is linear or non-linear. In 3 sentences or two, describe what information the standard deviation of errors provides. When the correlation between two variables is -1.0, what will the standard deviation of errors be? Why is this?

Refer to Exercise 11.25. (a) What proportion of the y variability is explained by the linear regression on x? (b) Find the sample correlation coefficient. Exercise 11.25 We all typically go to the shortest line in the grocery store. Data were collected on the number of carts ahead in line and the total time to check out (minutes), including time in line, on five occasions. (b) Test H0: β1 = 0 versus H1: β1 ≠0 with α = .05. (c) Estimate the expected y value corresponding to x = 3 carts and give a 90% confidence interval.
