9.3.6 The thicknesses of n = 41 glass sheets made using
process A are measured and the statistics = 3.04 mm
and s, = 0.124 mm are obtained. In addition, the
thicknesses of m = 41 glass sheets made using process B
are measured and the statistics ỹ = 3.12 mm and
Sy = 0.137 mm are obtained. Use a pooled variance
procedure to answer the following questions.
