For 129 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 9 bottles. The average across all 1,161 bottles (129 days, 9 bottles per day) was 59 degrees Fahrenheit. The standard deviation across all bottles was 1.1 degrees Fahrenheit. When constructing an X-bar chart, what would be the upper control limit? Note: Round your intermediate calculations and final answer to 4 decimal places
