process is working You must write a formula that references the assumed parameters. When we say almost all, we mean 99.2% of data, which is contained between i 3 SE of the population mean. write the formula for the lower limit in cell E19, and for the upper liruit in F19. See equation 2.2 on page 320 of our text for guidance. 2 points: Based on comparing the sample mean of tire process with your answer to part 1:, does it appear that the process is working properly? W'rite the word Yes or No in cell E21. 5 points: The engineering specifications provide that a gasket should be between 395 mm and 4GB mm, otherwise a gasket is defective. Assuming the process is working correctly; find the probability that a randomly selected gasket is not defective. Use Excel's built-in function for the Normal distribution to answer the question. and place the value in cell J2. 5 points: The engineering specications provide that a gasket should be between 395 rrrnr and 4GB mm, otherwise a gasket is defective. Assuming the process is working correctly; find the probability that a randomly selected gasket is defective. Use Excel's built-in function for the Normal distribution to answer the question. and place the value in cell J4
