Measurements were as follows: Serum Cholesterol (mg/ml) Subject Lab 1 Lab 2 1 296 318 268 287 3 244 260 4 275 279 5 245 245 285 289 7 255 249 8 245 295 262 271 10 180 11 190 Can we conclude that the cholesterol levels reported by Lab 2 are higher than the cholesterol levels reported by Lab 1 (at a =0.05)? Assume variances are equal.
