Needing help on these 3 questions listed below and how to get to the answer. All the information is list below to solve the question.

Situation 1 (Cans)

Repeated samples are taken from a can manufacturing process to determine if the cans are meeting specifications of being round = no distortions from being cylindrical and can hold pressure.Twenty samples are collected and 150 cans are taken in each sample.We are looking for the proportion of cans that do not conform to our specifications.See Can data in the Excel Data posted in BBL. (P Chart)

Situation 2 (Paint)

We are interested in monitoring a process that paints window frames, focused on the number of imperfections on each window frame.A sample of 25 window frames are collected and imperfections on each frame is noted.See Paint data in the Excel data posted in BBL. (C Chart).

Question 2. What is the LCL for the Can process?

Question 3. If I take 4 more samples FOR THE CAN PROCESS and if the proportions for these four samples are as follows; 0.062, 0.029, 0.031, and 0.071; does this indicate the process is still in control?

Question 4. For the paint process, what is the LCL?
