The article An Automatic Visual System for Marble Tile Classification (L. Carrino, W. Polini, and S. Turchetta, Journal of Engineering Manufacture, 2002:10951108) describes a measure for the shade of marble tile in which the amount of light reflected by the tile is measured on a scale of 0255. A perfectly black tile would reflect no light and measure 0, and a perfectly white tile would measure 255. A sample of nine Mezza Perla tiles were measured, with the following results: 204.999 206.149 202.102 207.048 203.496 206.343 203.496 206.676 205.831 Is it appropriate to use the Students t statistic to construct a 95% confidence interval for the mean shade of Mezza Perla tile? If so, construct the confi- dence interval. If not, explain why not.

Week 3 EDA for 2-Variable Data: - 2-variable data – when you have two measurements for each individual - An association (relationship) exists when values of a certain variable are more likely to occur when you have certain values of another variable - Explanatory...
