Question

a set of data has a mean of 12 and a standard deviation of 3. a data point of the set has a z - score of 1.3. what does a z - score of 1.3 mean? the data point is 1.3 standard deviations away from 3 the data point is 1.3 standard deviations away from 12. the data point is 3 standard deviations away from 1.3. the data point is 3 standard deviations away from 12.

Explanation:

The z - score represents the number of standard deviations a data - point is from the mean. Given a mean of 12, a standard deviation of 3, and a z - score of 1.3, it means the data point is 1.3 standard deviations away from the mean (which is 12).

Answer:

The data point is 1.3 standard deviations away from 12.
