Quality - Statistics Project ExampleStill from Table II-A, the maximum locate number is located where the raw with N code letter intersects with 1.5 percent this number is 14, which is the maximum locate number.To estimate the producers risk, we shall use binomial distribution Table. Since we shall require n = 15 as the sample size, we shall go to the row where n = 5. In the x Colum, we shall select 2, assuming that we shall not allow more than two defects. To get the producers risk, we shall locate the value that corresponds to 0.05, which is the AQL - this value is 0.97. Therefore, the producers risk = 100-97 = 3% or 0.03.This is a two-tailed test because the vapid hypothesis will be rejected if the sample mean is either too large or too small there are two outcomes that will lead to rejection of the null hypothesis.Considering the two-tailed test, we shall be interested in establishing whether the p-value is less than -2.5 or greater than 2.5 Using t Distribution Table, we fin d that P (t 2.5) = 0.9885 and P(t -1.77) = 0.9885 Therefore, p-value = 0.9885*2 =
