Exhibit C The following data represent the number of flash drives sold per day at a local computer shop and their prices. The Exhibit C The following data represent the number of flash drives sold per day at a local computer shop and their prices. The data is used to develop a regression model to predict the number of flash drives sold based on price. Some of the intermediate calculations are provided below: 62 Tttt 12 Price in S Units Sold 1ISG 34 36 4 32 6 12 25 900 35 5 30 270 23. Based on the data in Exhibit C, the regression equation is A) Unit sold- 32.4655+0.8103 Price B) Units sold 32.4655-0.8103 Price C) Units sold- 38.1887-0.8868 Price D) Price 32.4655-0.8103 Units sold E) Price 38.1887+0.8868 Units sold 24. Based on the data in Exhibit C, if the price is set at $33, the predicted number of flash drives sold per day is (round to a whole number) A) 10 B) 59 C) 6 D) 9 E) 67 . Based on the data in Exhibit C, what is the correlation coefficient (r)? A) -0.85 B) 0.85 C)-0.92 D) 0.92 E)-0.65
