![A psychologist believes that youths identified as
lesbian, gay, or bisexual already know their sexual
orientation before they turned 18. To verify this,
she took a random sample of 654 young adults
that identified as lesbian, gay, or bisexual and
asked them the age when they first realized their
sexual orientation. It is known that the mean age
when a young adult first realized they might be
lesbian, gay, or bisexual is normally distributed.
