For 100 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 10 bottles. The average across all 1000 bottles (100 days, 10 bottles per day) was 45 degrees Fahrenheit. The standard deviation across all bottles was 0.7 degree. Round your final answer to 4 decimal places.) When constructing an X-bar chart, what would be the upper control limit?
