For $101$ 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 $909$ bottles $(101$ days, $9$ bottles per day$)$ was $58$ degrees Fahrenheit. The standard deviation across all bottles was $8$ degree.
