Ugh, I hate these types of questions. There are so many steps involved, and it's easy to make a mistake somewhere. I'll just have to take it slow and double-check my work.
This looks straightforward enough. I'm pretty confident I can solve this by applying the standard control chart formulas. I just need to make sure I plug in the numbers correctly.
Hmm, I'm a bit unsure about how to approach this. I know we need to find the control limits, but I'm not sure of the exact formula to use. Maybe I should review my notes on statistical process control.
Okay, let me think this through step-by-step. I'll need to calculate the mean and standard deviation of the defect data, then use those to find the control limits.
