: Can you please tell me If I set this up and worked it out correctly.
Question:
Analyzing customer service. The distribution of times that customers spend waiting in line in a supermarket has a mean of 3.6 minutes and a standard deviation of 1.2 minutes. For this distribution find the raw score that corresponds to a z-score of -1.3.
Here is how I set it up
-1.3= x-3.6 divided by 1.2
Then i multiplied both sides by 1.2 giving me the equation of
-1.56 = X-3.6,
-1.56 +3.6 = X,
2.04 = X
X = 2.04
Raw score is 2.04 that corresponds to the z-score of -1.3.
Can you tell me if this is the correct way to work this out?
Thank You.
