Refer to the paint thickness problem 17.49. Assume μ = σ 1.00 and 5 0.07. Use the following 35 individual observations on paint thickness to answer the questions posed.

(a) Prepare a histogram and/or normal probability plot for the sample.

(b) Does the sample support the view that paint thickness is a normally distributed random variable?

(c) Are the mean and standard deviation about as expected?
