Question

Consider two production lines with fraction of nonconformities in accordance with LSL, USL.

Production Line 1

P1=0.2

Production Line 2

P2=0.2

Suppose that two independent random samples of 100, 120 are taken from production lines 1 & 2, respectively. Also, Let’s 10, and 12 represents the number of nonconformities in the samples.

Develop a procedure for testing the hypothesis that fraction of nonconforming production for both lines (P1, P2) by Normal Distribution approximation. (Alpha=5%)

Make hypothesis a test of whether the individual proportion is correct
