Question

A normal distribution curve has a mean of 18 and a standard deviation of 5. What value is 2 standard deviations above the mean?

8
23
13
28

Answer 1

The value that is two standard deviations above the mean on a normal distribution curve with a mean of 18 and a standard deviation of 5 is 28.

Step-by-step explanation:

To find the value that is two standard deviations above the mean on a normal distribution curve with a mean of 18 and a standard deviation of 5, you would perform the following calculation:

Mean + (2 × Standard Deviation) = 18 + (2 × 5)

= 18 + 10

= 28.

Therefore, the value that is two standard deviations above the mean is 28.
