Answer:
True.
Explanation:
We have been given a statement and we are asked to determine whether our given statement is true or false.
Statement:
A z-score of 1.0 corresponds to a value one standard deviation from the mean.
We know that z-score of a data set represents how many standard deviation a data point is above or below mean.
Since the z-score of a data set is 1.0, so it represents that the data is 1 standard deviation above mean.
Therefore, our given statement is true.
