For 129 consecutive days, a process engineer measured the temperature of champagne bottles as they are made ready for serving. Each day, she took a sample of 7 bottles. The average across all 903 bottles (129 days, 7 bottles per day) was 40 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? degrees Fahrenheit

ANSWER IS NOT 43.9000 DEGREES. Thank you!
