Additional problem 1: A manufacturer claims that

Additional problem 1: A manufacturer claims that a process mean is 75 . It is desired to test this claim on a continuous basis by periodically taking a single measurement of the process quality characteristic (X). Given this sampling scheme, develop lower and upper cut-off limits (X10 and Xhi ) for the desired hypothesis tests. The standard deviation of distribution of X is known to be 6 . Assume a risk level, , of 0.05. Create an OC curve, as discussed in class, to show the performance of the sampling scheme. Use Excel to create your OC curve.
