For this case we must simplify the following expression:
By definition we have that the distributive property establishes that:
So, if we have:
-2 (x-3)
We take into account the law of multiplication of signs:
So:

Answer:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
Step-by-step explanation:
We have a population with mean 390 and standard deviation 45.83.
Samples of size n=49 are taken.
The parameters of the sampling distribution are:
First, we have to calculate the z-score that satisfies:
This z-score, looked up in a standard normal distribution table, is z=-0.915.
Then, we can calculate the sample mean as:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
