Homework Help: Confidence Intervals

Posted by melanie on Friday, June 20, 2008 at 10:41pm.

Over the last 15 Major League Baseball seasons, the mean number of strikeouts by the American League leader is 258.5. Assuming that the number of strikeouts by the league leader is normally distributed and the standard deviation for all seasons in all leagues is 34.9, find the 82% Confidence Interval and the 93% Confidence Interval for the mean.

I got as far as 1-.82=.18 & 1-.93=.07. However, I'm not sure I have even that part right. Plz help!
