Aset of data has a mean of 0.5 and a standard deviation of 0.01. a data point of the set has a z-score of 2.5. what does a z-score of 2.5 mean? a. the data point is 0.01 standard deviations away from 2.5. b. the data point is 0.01 standard deviations away from 0.5. c. the data point is 2.5 standard deviations away from 0.01. d. the data point is 2.5 standard deviations away from 0.5.

D. The data point is 2.5 standard deviations away from 0.5.

Step-by-step explanation:

Z-score is the measure of how many number of standard deviations, the data point, is away from the mean. It also measures how many standard deviations below or above the population mean, a raw score is.

Given, a set of data has a mean (μ) of 0.5 and a standard deviation (σ) of 0.01 with a data point of the set has a z-score of 2.5.

i.e the data point is 2.5 standard deviations away from the mean 0.5.
