Answer:
Automated menu
Live agent menu
So then we can conclude that we have lower variation for the Live agent menu since the coefficient of variation is lower compared to the Automated menu
Step-by-step explanation:
We can solve this by case
Automated menu
Data: 11.7 7.4 3.9 2.9 9.2 6.3 5.5
We can begin calculating the mean with the following formula:
And replacing we got:
Now we can calculate the standard deviation with the following formula:
And replacing we got:
Now we can calculate the coeffcient of variation with this formula:
And replacing we got:
Live agent menu
Data: 6.2 2.9 4.4 4.1 3.4 5.2 3.7
We can begin calculating the mean with the following formula:
And replacing we got:
Now we can calculate the standard deviation with the following formula:

There's actually a secret trick to doing it without using the complete the square method. There's a formula and it always works. My teacher taught me it and I used it a lot in the ALG1 EOC and was VERY helpful. I guess ur prepping for the eoc ri xD
So the "hack" is the first 2 attachments.
it's important to know the typical method, so the typical one is the last attachment
