I think the correct answer to your math question is this: Mrs. Yero needs 1 and 1/3 cup of buffalo sauce for her dip for the party.
f(-2) means the x value is -2 and you need to find the y value at that point.
At x = -2 the line crosses the y axis at y = 2
f(-2) = 2
The probability distribution of normal distribution is given by,
f(x) =

Where a = mean = 16 and α = standard deviation = 3
In normal distribution, skewness is zero. That is, distribution is symmetric.
Therefore, mean, median and mode coincide at a point in case of normal distribution.
50th percentile is same as median or mean or mode
Therefore, 50th percentile = 16
