Wait, how can there be no control limits?

Control limits are usually calculated, not "none."

Sample size is 85, so we need to calculate properly!

I’m a bit confused about the “none” options. I thought we always had to calculate specific limits, but maybe I’m missing something.

I feel like none of the options seem right based on what we practiced. Control limits should be based on the average defects, right?

I think we did a similar question where we had to find the average and then the control limits. I hope I can remember the formulas!

I remember we calculated control limits in class, but I'm not sure how to apply it here with the defects.

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.

Hold up, did someone say 'control limits'? I thought this was a cooking class. Where's the recipe for the perfect soufflé?

Hmm, this seems like a straightforward statistical question. I'm going with B) 12.6 and 25.2. Anything else would be a bit of a stretch.

D) none of the above? Really? That can't be right. There has to be a valid set of control limits for this process.

I think the answer is B) 12.6 and 25.2. The control limits should be calculated based on the sample size and the number of defects.
