Question 421542: Can you please assist with this problem. I am unsure if I have the correct answer?
The owner of an appliance store uses a normal distribution with mean 10 and variance 9 to model the weekly net sales (in units of $1000). The owner needs $3500 a week to pay his staff. Determine the probability that the weekly net sales will not be enough to pay the whole of this amount.
Thank you so much!

-------
z(3500) = (3.5-10)/9 = -0.7778
-----
P(x < 3.5 thousand) = P(z < -0.7778) = 0.2184
