Answer:
upper control limit = 13.34
Step-by-step explanation:
The c-chart is used to check the change in the number of recorded calls per day
First find out the center line
c = sum of recorded calls/number of days
c = (3 + 0 + 8 + 9 + 6 + 7 + 4 + 9 + 8)/9
c = 54/9
c = 6
The upper control limit for 3σ is
upper control limit = c + 3√c
upper control limit = 6 + 3√6
upper control limit = 13.34
Therefore, the upper control limit for the 3-sigma c-chart is 13.34.

<h3>What is The Golden Notebook?</h3>
The Golden Notebook is a 1962 book by Doris Lessing, a British author. It investigates mental and societal breakdown, much like her two succeeding books, which Margaret Drabble referred to as Lessing's "inner space fiction" in The Oxford Companion to English Literature. In addition to an extensive investigation of communism and the Communist Party in England from the 1930s to the 1950s, the novel also examines the nascent sexual revolution and women's liberation movements. It also contains anti-war and anti-Stalinist undertones. The Golden Notebook was listed among the top 100 English-language books published since 1923 by TIME magazine in 2005. Other languages that it has been translated into include French, Polish, Italian, Swedish, Hungarian, and Hebrew.
