Chapter 10, Problem 10.7.14(choose chapter or problem)
Composite Material Properties In a research report on the effect of moisture on a certain kind of composite material, it is reported that in 80% of cases the effect is minimal, in 15% of cases the effect is strong, and in the remaining 5% of cases the effect is severe. An experimenter tested these claims by subjecting 800 samples of the composite material to moisture, and the results are given in DS 10.7.8. (a) Perform a chi-square goodness of t test to examine whether these experimental results are consistent with the claims made by the research report. (b) Use the experimental results to construct a 99% one-sided condence interval that provides an upper bound on the probability of a severe moisture effect.
