Which symbol is used to represent the density curve?
Af(x)
BP(A)
CS(n)
DR(t)
Answer & Solution
Correct answer: A. f(x)
1. The density function has a standard notation.
2. The symbol f of x is used to represent the curve.
3. It is the function that corresponds to the graph.
4. The density function f of x is used to draw the graph of the distribution.
