- An engineer claims the population mean of a certain batch process is 400 grams. To check his claim he takes a random sample of 36 batches and he is satisfied with his claim if his t-value lies in the range (t0.90, t0.10). Should he be satisfied with his claim if his random sample has a sample mean of 430 grams and a sample standard deviation of 90 grams?Use the ALEKS calculator to solve the following problems.
