For 133 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 665 bottles (133 days, 5 bottles per day) was 60 degrees Fahrenheit. The standard deviation across all bottles was 0.8 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? not attempted degrees Fahrenheit
