Line has a gradient of 2, so equation becomes 16 A – When , so substitute into equation. Equation is 17 A 18 From Calculator C Mean = 21.6; Standard deviation = 1.8 19 B 20 A4 and B4 are both text cells, so would not affect the calculation of Average D Daily and Total Pay. D4 is the hours worked, and since the pay is piecework, this would make no change to the Pays. E4 is the Rate per basket and would be used to calculate the pays, so would affect both values. 21 C 22 D
