Use this data to create regression models to answer all of the questions below. a: (sleeping bags) p ($) C (55) 95 240 13,000 120 235 14,300 180 155 18,500 220 50 21,000 Revenue Model Use the price model above to construct a revenue model. Find a model for the weekly revenue, using $ as the independent variable. NOTE: Do not calculate another regression. Use the price equation to nd a model for revenue R($) = p - :13. R(:I:)=p-m=(a+b$+ca;2)$=aw+bsc2+6933 Use this revenue model to answer questions 3-8 below. Question 3 3 pts Use the revenue model above to answer this question. What is a?
