Answer 2

The data point is 1.6 standard deviations above the mean.

Explanation:

Z-score

It is the number of standard deviations from the mean that a data point is. It's a measure of how many standard deviations below or above the population mean a raw score is.

A Z-score is also known as a standard score and it can be placed on a normal distribution curve.

As in this case the Z-score is +1.6, so it means the data point is 1.6 standard deviations above the mean.
