A random sample of 41 glass sheets is obtained and their
thicknesses are measured. The sample mean is =3.04 mm and the sample
standard deviation is s=0.124 mm.
Construct a 95% two-sided t -interval for the mean
glass thickness.
Do you think it is plausible that the mean glass thickness is
2.80 mm? why or why not?
