Math Problem Statement

For the continuous distribution below, what does the shaded area represent?

Solution

The question is asking about the shaded area under a continuous distribution curve. Based on the image, the shaded area appears to be between x=6x = 6 and x=7x = 7 on the horizontal axis.

To answer the question:

  • The shaded area under the curve represents the probability that the variable xx lies within a certain range. Specifically, since the shaded area is between 6 and 7, this corresponds to the probability P(6<x<7)P(6 < x < 7).

Thus, the correct answer is:

P(6<x<7)P(6 < x < 7).

Tip: For continuous distributions, the probability of a single point (e.g., P(x=6)P(x = 6)) is always zero because probability is represented by the area under the curve over an interval.
