Chapter 8.3, Problem 37E
The accompanying data on cube compressive strength (MPa) of concrete specimens appeared in the article “Experimental Study of Recycled Rubber-Filled High-Strength Concrete” (Magazine of Concrete Res., 2009: 549–556):
- a. Is it plausible that the compressive strength for this type of concrete is
normally distributed ? - b. Suppose the concrete will be used for a particular application unless there is strong evidence that true average strength is less than 100 MPa. Should the concrete be used? Carry out a test of appropriate hypotheses.

Artificial joints consist of a ceramic ball mounted on a taper. The article "Friction in
Orthopaedic Zirconia Taper Assemblies" (W. Macdonald, A. Áspenberg, et al., Proceedings
of the Institution of Mechanical Engineers, 2000: 685-692) presents data on the coefficient
of friction for a push-on load of 2 kN for taper assemblies made from two zirconium alloys
and employing three different neck lengths. Five measurements were made for each
combination of material and neck length. The results presented in the following table are
consistent with the cell means and standard deviations presented in the article.
