Thirty-five samples of 25 packages each at the Bakery Bread, Inc. were inspected, and 25 items were found to be defective. Calculate the centerline for a p-chart. Please type your answer in two decimal places.

The centre line of the p chart is 0.03

Step-by-step explanation:

Given

Samples, n = 35

Packages, p = 25

Defective, d= 25

The centerline of a p-chart is the expected value of the proportions and is calculated based on sample data.

In this case, it is calculated as;

d/(p * s)

= 25/(25*35)

= 1/35

= 0.02857142857142857142857

= 0.03 approximated

Hence, the centre line of the p chart is 0.03

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
