# Question: Consider the following sample of 25 observations on the diameter

Consider the following sample of 25 observations on the diameter x (in centimeters) of a disk used in a certain system.

The 13 largest normal scores for a sample of size 25 are 1.965, 1.524, 1.263, 1.067, 0.905, 0.764, 0.637, 0.519, 0.409, 0.303, 0.200, 0.100, and 0. The 12 smallest scores result from placing a negative sign in front of each of the given nonzero scores. Construct a normal probability plot. Does it appear plausible that disk diameter has a normal distribution? Explain.
