The highest rate of nondefective CD players that the manufacturer could claim under the given condition is 98.2%. This is because the critical value for a left-tailed hypothesis test with a significance level of 0.05 and a sample size of 100 is 1.645. The manufacturer could claim a rate of nondefective CD players of 98.2% because this rate is not significantly different from the sample rate of 96% at the 0.05 significance level.
