Problem 3
Ten measurements of an impurity concentration in a process stream have been
recorded. The sample mean is 87ppm and the sample standard deviation is ±13 ppm.
Consider the null hypothesis that the impurity concentration has a true mean μo.
Part A: Desired Probability that the sample mean will satisfy the null hypothesis:
P = 0.4
Part B: Using the chart below, determine the4 highest value of the true mean that will lead
to the null hypothesis being accepted with the probability assigned in Part A

Problem 2
A chemical reactor system has been designed to perform optimally when operated
at 150°C. The hypothesis test that will be used for evaluating the operating temperature will
rely on 10 successive temperature measurements and will assign a 95% confidence
interval for the result. The reactor system is judged to have a standard deviation of ±3°C.
Part A: Actual operating temperature of the process T[°C] = 152.90
Part B: What is the probability that the hypothesis test for operating at 150°C described
above will give a false acceptance (i.e., a type II error)?
Problem 1
An airport is served with an average of 10 departures per day to your desired
destination. However, all these flights leave at random times. You are trying to decide how
long you are willing to wait to catch the next flight after you arrive at airport.
Part A: Acceptable waiting time: T [min] = 78min
Part B: What is the probability there will be exactly one departure during this waiting time?
Part C: What is the probability there will be exactly no departure during this waiting time?
Part D: Which calculation (B or C) should you use to make your decision to wait or leave?
