Is it appropriate to use the Student's t statistic to construct a 95% confidence interval for the mean shade of Mezza Perla tile? If so, construct the confidence interval. If not, explain why not.
The article “An Automatic Visual System for Marble Tile Classification 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 0-255. 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
