-The Z scores can be used to identify outliers.

Accepted Answer

Z scores can be used to identify outliers by calculating how many standard deviations away from the mean a data point is. Any data point that has a Z score of greater than 3 or less than -3 is considered an outlier. Therefore, in this case, we can calculate the Z scores for each rate of return and identify any outliers in the data set.

-As a general rule,a value is considered an extreme value if its Z score is less than -3.

Accepted Answer

A Z score of less than 3 indicates that a value is within 3 standard deviations from the mean, which is not necessarily considered extreme. An extreme value is usually defined as being much further from the mean, often beyond 3 or 4 standard deviations. Therefore, the statement in the question is false.
