Answer:

The z- score for a value of 3.99 will be 3.38.

Step-by-step explanation:

It is given that the mean of a set of data is -3.82 and its standard deviation is 2.31.

Thus, the value of the z-score=\frac{value-mean}{standarddeviation}

=\frac{3.99-(-3.82)}{2.31}

=\frac{3.99+3.82}{2.31}

=\frac{7.81}{2.31}

=3.38

Thus, the z- score for a value of 3.99 will be 3.38.
