Question 8 Provide an appropriate response. A manager wishes to determine the relationship between the number of years her sales representatives have been with the firm and their average monthly sales (in thousands of dollars). Find the equation of linearregression and interpret its slope. Years with firm, x 2 3 10 15 3 11 Sales, V 31 33 78 62 65 61 48 55 120 O y = 3.529x+37.9, s= 3.529; Monthly sales increase by $3.529 per year. O y = 0.832x-317.7, s= 317.7; Monthly sales increase by $832 per year. O y =-0.772x+210.8, s= -0.772; Monthly sales decrease by $772 per year. O y=-0.281x+317.8, s= -0.281; Monthly sales increase by $317.8 per year. A Moving to another question will save this response
