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

people were working. what was the actual amount of sales? The actual amount of Sales was 1
(foound to the nearect dollar as needed). 9) State and interpret the R 2 value in context. The R 2
value is W. This means that 5 of the the response varistle, is explained successtuly or using the
explanatory variable (Round to one decimal place as needed.) Data and Regression Analysis
