In an electronics company that produces transistors,1000 transistors are inspected at regular intervals.The proportion of nonconforming transistors produced by the process,estimated from data collected in a 1-month period,is = 0.0026.What would be the value of the center line for a p chart of future samples of size 1000?

For a p chart, the center line is the average proportion of nonconforming units across all samples. Since the proportion of nonconforming units in the data collected in the 1-month period is 0.0026, this would be the best estimate for the center line of future samples of size 1000. Therefore, the answer is A) 0.0026.
