Omar is a quality control expert at a factory that paints car parts. He knew that 20% of parts were being painted with an error, so he made a change in the painting process. After the change, he wanted to test H, :p=0.2 versus H, p<0.2, where p is the proportion of parts that were being painted with an error Omar took a sample of 400 parts and found that 16% of them had an error. He used these results to calculate a test statistic of 2 = -2.00 and a P-value of approximately 0.023. Assume that the conditions for inference were met. Is there sufficient evidence at the a = 0.05 level to conclude that less than 20% of the parts are being painted with an error? Choose 1 answer Yes, because 0.023 <0.05. Yes, because 16% < 20%. No, because 0.05 0.023. No, because 0.16 0.05.
