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.
