Question

the graph of a uniform distribution is shaped like
a straight line
the letter n
a bell
a pyramid
a parabola
an exponential function

Explanation:

A uniform distribution has a constant probability density function over a given interval. Visually, this appears as a straight horizontal line (since the height, representing probability density, is constant) between the lower and upper bounds of the distribution. The "bell" shape is for normal distribution, "pyramid" doesn't fit, "parabola" and "exponential function" are for other distributions, and "letter N" is not a standard distribution shape.

Answer:

a straight line
