They measure the download time of their software 6 times a day for 5 days as shown in the table below. The standard deviation of the download time is 6. Day 1 36 37 49 46 41 47 UCL of X LCL of X Download time in seconds Day 3 40 46 Day 2 45 40 UCL for LCL for 50 41 41 45 42 44 36 47 Day 4 50 39 45 45 37 39 Day 5 44 36 42 35 a. Construct an appropriate control chart (with two-sigma limits) to demonstrate if the download time is within the company's expectation and the process is in control. (Round your answer to two decimal places.) 50 41 b. Do you think the download time on any of these days had a wide range? Use a control chart to support your answer.
