A major package delivery company claims that at least 95 percent of the packages it delivers reach the destination on time. As part of the evidence in a lawsuit against the package company, a random sample of n = 200 packages was selected. A total of 188 of these packages were delivered on time. Using a significance level of 0.05, the critical value for this hypothesis test is approximately 0.90.

The critical value in hypothesis testing is typically found from a statistical distribution (e.g., z-distribution, t-distribution) and represents the threshold for rejecting the null hypothesis. It is not calculated as a percentage like 0.90 but rather as a value from these distributions corresponding to the chosen significance level (e.g., z = 1.96 for a two-tailed test with α = 0.05). The statement mixes up concepts related to hypothesis testing.
