can you help with this

The electric car company also wants to control the quality of the current battery manufacturing system, so it gathered 15 batches with size 3 from the production line and calculated the following values for the lifespan of products. 15 15 x, = 5400 > R; - 50 i=1 i=1 (a) Set up the control charts using these data. (b) If that the process exhibits statistical control. Estimate the process mean and standard deviation. (c) If the lifespan is normally distributed with specifications at 361±7, calculate the fraction nonconforming produced.
