For 120 consecutive days, a process engineer has measured the temperature of cham- pagne bottles as they are made ready for serving. Each day, she took a sample of 8 bottles. The average across all 960 bottles (120 days, 8 bottles per day) was 46 degrees Fahrenheit. The standard deviation across all bottles was 0.8 degree. When constructing an X-bar chart, what would be the upper control limit?
