Montoya (2007) asked 56 men and 82 women to rate 21 different body parts on a scale of 1 (no opinion) to 5 (very desirable). They found that men and women rated the eyes similarly, with an average rating of about 3.77 ± 1.23 (M ± SD). Assuming these data are normally distributed,
(a) What percentage of participants rated the eyes at least a 5 (very desirable)?
(b) What percentage rated the eyes at most a 1 (no opinion)?
