Ron,
The precalculated optimizer statistics are flagged as questionable at export
time if:
-> There are row errors while exporting
-> The client character set or NCHAR character set does not match the server
character set or NCHAR character set
-> A QUERY clause is specified
-> Only certain partitions or subpartitions are exported
Also, you should have a look at this doc;

I have a new Oracle 9.2 database that I am exporting. I keep getting the
EXP-00091: Exporting questionable statistics. error.
I ran catexp on the database, but that didn't;t help.
Can someone tell my how to get rid of the error?
Thanks!
Ron
