The article “An Automatic Visual System for Marble Tile Classification” (L. Carrino, W.
Polini, and S. Turchetta, Journal of Engineering Manufacture, 2002:1095–1108) 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:
204.999206.149202.102207.048203.496 206.343203.496206.676205.831
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.
