Question

Graduate management aptitude test (gmat) scores are widely used by graduate schools of business as an entrance requirement. suppose that in one particular year, the mean score for the gmat was 473, with a standard deviation of 104. what values are three standard deviations within the mean?

Answer 1

The values that exist two standard deviations above and below the mean are 681 and 265.

How to determine the values?

The given parameters exist:

Mean = 473

Standard deviation =104

The values above and below the mean exist calculated utilizing:

$x=\bar{x} \pm n \sigma$

In this case n = 2.

So, we have, $x=\bar{x} \pm 2 \sigma$

The value above is:

x = 473 + 2 $*$ 104 = 681

The value below is:

x = 473 - 2 $*$ 104 = 265

Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.
