A bank manager wanted to double-check her claim that recent process improvements have reduced customer wait times to an average of 3.3 minutes, with a standard deviation fo 1.0 minutes. To test this, she randomly sampled 25 customers and recorded their wait times. The average wait time of the customers in the sample was 3.8 minutes. Assuming the claim about wait time is true, what is the probability that a random sample of n=25 customers would have a sample mean as large as or greater than 3.8 minutes? What should the manager conclude about her claim?
