Question 1199055: Q:The amount of barbeque sauce on VLC Spicy Wings is normally distributed with a mean of 20 mL (you didn't have time to calculate the standard deviation). What would you expect to find more of in a basket: wings with more than 18 mL of sauce or wings with less than 21 mL of sauce? Explain.
I'm not sure where to start at all, any guidance would be much appreciated.

~~~~~~~~~~~~~~~~
Each normal distribution curve is a bell-shaped curve, symmetrical about the mean value score on horizontal axis.
It means that the area under this curve on the left from the mean value
is the same as to the right from the mean value.
Now, 18 mL is 2 mL on the left from the mean value, while 21 mL is 1 mL on the right
from the mean value.
From it, and based on symmetry and common sense, the probability to have 18 ml or more
is greater than the probability to have 21 mL or less.
