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

By definition, the standard form of a polynomial is given by:
We then have the following polynomial:
Rewriting in its standard form we have:
We realize that the polynomial has three terms, therefore, it is a trinomial.
The largest exponent of the polynomial is three and therefore we have a trinomial of degree three.
Answer:
Three degree trinomial.
