Question

the graph of a uniform distribution is shaped like

a pyramid

a straight line

an exponential function

the letter n

a parabola

a bell

Explanation:

A uniform distribution has a constant probability density function over a given interval. Its graph (probability density function) is a horizontal straight line (since the probability density is constant) within the interval of the distribution. A pyramid - shaped graph is more related to a triangular distribution. An exponential function's graph is a curve that either increases or decreases exponentially. The letter "N" - shaped graph is not related to a uniform distribution. A parabola is the graph of a quadratic function. A bell - shaped curve is the graph of a normal (Gaussian) distribution, not a uniform distribution. So the correct shape for a uniform distribution's graph is a straight line.

Answer:

a straight line
