Question 4
Company records show that the proportion of defective parts has historically been 5%, however a
quality control engineer believes that due to budget cuts these numbers have increased. To test this
claim a random sample of N = 15 parts will be taken and if more than two defective parts are found
the inspector will conclude that the proportion of defective parts has increases. If the true
probability of a defective part is in fact p = 10% what is the power of the test?
96.4%
