Rodrigo-Swift Essentials (RSE) Inc. produces and sells "dj vu" moisturizing lotion. COO Jack Antonoff assigned line supervisor Zo Kravitz the task of taking a sample of 5 randomly selected tubes of lotion from the production line every day over 6 days, measuring the volume of lotion in oz., and recording it. Based on the data collected, and provided to you in an Excel file Download Excel file(also shown below), Zo would like your help in computing the Center Line values (only, and NOT the lower and upper control limits) for the (1) X-Bar and (2) R (mean and range) statistical process control (SPC) charts based on these 6 samples (also called sub-groups). Please do all calculations and report your final answers for the two values keeping 4 places after the decimal if needed. No need to upload any file as part of your response or show any calculations in your submission. Do describe briefly in words how you went about doing your calculations (so you can get partial credit in case your final values are incorrect). An interpretation of the values for the two center lines is not required
