A researcher is interested in determining the effect of two factors. The percentage of Lysine in the diet andPercentage of Protein in the diet have on Milk Production. Seven animals (cows) are selected at random for the experimentwhich is to be carried out over seven three-month period

The data is tabulated in this form Period Cows 1 2 3 4 5 6 7 1 Aa = 204 BE = 136 CB = 150 Do = 104 Ex = 117 Fy = 119 GS = 132 2 BB = 181 C = 105 DX = 125 Ey = 164 FS = 194 Ga = 150 Ag = 113 3 Cx = 132 Dy = 166 ES = 179 Fa = 157 Ge = 161 AB = 140 Bo = 102 4 DS = 242 Ea = 272 FE = 236 GB = 166 Ap = 295 BX = 225 Cy = 207 5 EE = 196 FB = 149 Go = 193 Ax = 145 By = 109 CS = 181 Da = 180 6 Fp = 134 GX = 121 Ay = 152 BS = 227 Ca = 146 De = 278 EB = 197 7 Gy = 143 AS = 186 Ba = 135 CE = 185 DB = 106 Ed = 154 Fx = 110 Latin = Protein; Greek = Lysine, Row = Cows, Columns = Period
