1.) Consider the following sample of observations on coating
thickness for low-viscosity paint.
Assume that the distribution of coating thickness is normal (a
normal probability plot strongly supports this assumption).

(a) Calculate a point estimate of the value that separates the
largest 10% of all values in the thickness distribution from the
remaining 90%. [Hint: Express...
