Every day, you take a sample of 50 shipments that are ready to be shipped to the alumni and inspect them for correctness. Across all days, the average percentage of incorrect shipments is 5 percent. What would be the center line for a p-chart? multiple choice 40 50 0.05 2.5 None of these

Answer 1

Answer:

$Center\ Line = 0.05$

Step-by-step explanation:

Given

$n = 50$ --- daily samples

$days = 40$

Required

Determine the center line of the p-chart

The question states that, in all the 40 days; the average percentage of incorrect shipments is 5%

And the center line of a p chart is a measure of the expected value of all proportions

This implies that:

$Center\ Line = 5\%$

$Center\ Line = 0.05$
