Consider the accomparying data examining the relationshp between the anount of sales and the rumber of sales pecple working in a small bookstore. Complote parts a trough g below. Click the ioon to view the dota and regression analysis. a) Write the regression equation. Define the variables used in your equation. (Round to four decimal places as needed.) b) Interpret the siope in contoxt Select the correct choice below and fit in the ansmer box to complele your choice. A. On average, 1 additional sales person working in this bookstore is assodated with an herease in sales of 5 (Round to the nearest dotar as needed.) B. On average, an increase in sales of $1000 for this bookstore is associated with addesenal sales peopleperson woking. (Round to four decimal places as needed.) c) What does the yintercept mean in this context? is it meaningfut? A. It would mean that, on avorage, the bookstore would be predicted to have 1 of saies when a had 0 sales people woiking. It is not meaningful in this contaxt because the ithre would not sell books without sales people. (Round to the nearest dollar at needed.) a. If means that, on average, the bookstore would be predicted to have (Round to the nearest dollar as neoded) c. It means that, on average, the bookstore wouls be predicted to haye cales people working when it had salos of so. it is mearingtul in this contest because this vilue is gratee than cero (fiound to four decimal places as neoded) Consider the accompanying data examining the relationship betwoen the amount of sales and the nomber of sabes peoplo working in a small bockstork.
