Chapter 11, Problem 11.1.13

(choose chapter or problem)

A factory has three production lines producing glass sheets that are all supposed to be of the same thickness. A quality inspector takes a random sample of n =30 sheets from each production line and measures their thicknesses. The glass sheets from the rst production line have a sample average of x1 =3.015 mm with a sample standard deviation of s1 =0.107 mm. The glass sheets from the second production line have a sample average of x2 =3.018 mm with a sample standard deviation of s2 =0.155 mm, while the glass sheets from the third production line have a sample average of x3 =2.996 mm with a sample standard deviation of s3 =0.132 mm. What conclusions should the quality inspector draw?
