You are a manager at a restaurant and you want to see if there is a relationship between the number of hours your employees work and the number of sales they made. You collect the following data: Employees Hours Worked Sales Made (Y) X2 Laura 6 100 Sarah 8 120 Tim 10 140 Jimmy 12 160 Carter 14 180 Totals determine the correlation coefficient and determine if a statistically significant relationship exists between the two variables. If there is, then they must also supply the linear regression model.

19. You might think that increasing the resources available would elevate the number of plant spe- cies that an area could support, but the evidence suggests otherwise. The data in the accompany- ing table are from the Park Grass Experiment at Rothamsted Experimental Station in the U.K., where grassland field plots have been fertilized annually for the past 150 years (collated by Harpole and Tilman 2007).

Café Michigan's manager, Gary Stark, suspects that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Price $2.70 $3.40 $1.90 $4.10 $3.00 $4.00 Using simple linear regression, and given that the price per cup is $1.80, the forecasted demand for mocha latte coffees will be cups (enter your response rounded to one decimal place).
