A shop manager paid local radio stations to air a sales advertisement for one weekend. Since they charged different fees, there was a variation in the number of times the advertisement was aired. (Assume all stations are similar in contents). After that sales weekend, the manager wants to find out whether there is any linear association between the number of times the sales advertisement was aired at local radio stations and the sales figures in that weekend. Compute for the Correlation Coefficient (r). Find the regression equation. Then solve for: a) The sales if the number of airings is 8. b) The number of airings required to have a sales of 27,000 pesos. 1. r = Blank 1 2. y = Blank 2 + Blank 3 x a) Blank 4 pesos b) Blank 5 airings
