Abdullah is a quality control expert at a factory that paints car parts. He knows that 20 % 20% of parts have an error in their painting. He recommended a change in the painting process, and he wanted to see if this error rate had changed. He took a random sample of 400 parts painted in a month and found that 60 had an error. He wants to test H 0 : p = 0.2 H 0 :p=0.2H, start subscript, 0, end subscript, colon, p, equals, 0, point, 2 versus H a : p ≠ 0.2 H a :p =0.2H, start subscript, start text, a, end text, end subscript, colon, p, does not equal, 0, point, 2, where p is the proportion of all parts with the error in their painting that month.
