The experiment shows that there is still uncertainty about the difference in correlations. It could be that the correlation for females is as much as 0.49 higher. However, it could also be 0.15 lower.

- Compute the sample r's.

- Use an r to z' table to
convert the values of r to z'.

- Compute z'
_{1}- z'_{2}.

- Use a to z
table to find the value of
z for the level of confidence desired.

- Compute:

- Lower
limit = z'
_{1}- z'_{2}- (z)()

- Upper
limit = z'
_{1}- z'_{2 }+ (z)()

- Use an r to z' table to convert the lower and upper limits to r's.
