WebTo find the critical value, we need to first specify the level of significance (α). Let's assume α = 0.05, which means that we want a 95% confidence level. Since the sample size is greater than 30 and we know the population standard deviation, we can use the z-test to test the null hypothesis that the average payment time is still 40 days.
