Step-by-step explanation:

3x2x2=12
5x7x3=105

Answer:
2.35 calls
Step-by-step explanation:
The presented scenario can be modeled by a Poisson distribution with an average number of calls (μ) of 5.5 during the noon hour on Mondays.
Therefore, the standard deviation for the number of calls received, X, is given by:

The standard deviation of X is 2.35 calls.
+x on each side. Then -2 on each side. Then divide both sides by 6 and you have your answer
1379.52 is the answer to your question
