Question

The area under the density curve that lies to the right of 11 is 0.322. What percentage of all possible observations of the variable are at most 11?

Answer 1

Answer: 67.8%

Explanation:

The variables that are at most 11 will lie on the left of 11.

The percentage of the possible observations to the left will be:

= 1 - percentage to the right

= 1 - 0.322

= 0.678

= 67.8%
