For 113 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 1017 bottles (113 days, 9 bottles per day) was 60 degrees Fahrenheit. The standard deviation across all bottles was 0.5 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

upper control limit

Concept :

 where

where

Given :

She took a sample of per day is bottles.

The standard deviation of all bottles is degree.

Average across all bottles are degree Fahrenheit.

To find :

The value of the upper control limit (UCL)

Explanation :

Here, firstly we find the value of .

and

Now,

degrees.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
