The resilient moduli of 10 samples of a clay mixture are
measured and the sample mean is =19.50. If an experimenter wishes to use
a “known” value σ=1.0 for the standard deviation of the resilient
modulus measurements based upon prior experience, construct
appropriate 90%, 95%, and 99% two-sided confidence intervals for
the average resilient modulus μ. Compare the lengths of the
confidence intervals. Do you think it is plausible that the average
resilient modulus is equal to 20.0?
