For 103 consecutive days, a process engineer has measured the temperature of champagne bottles as they are made ready for serving. each day, she took a sample of 5 bottles. the average across all 515 bottles (103 days, 5 bottles per day) was 55 degrees fahrenheit. the standard deviation across all bottles was 1.3 degrees. (round your intermediate calculations and final answer to 4 decimal places.) when constructing an x-bar chart, what would be the upper control limit?
