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)?
