Visual sequential memory and poor spellers. Holmes, Malone, and Redenbach (20008) found that good readers and good spellers correctly read 93.8 ± 2.9 (M ± SD) words from a spelling list. On the other hand, average readers and poor spellers correctly read 84.8 ± 3.0 (M ± SD) words from the same spelling list. Assuming these are normally distributed,
What percentage of participants correctly read at least 90 words in the average readers and poor spellers group?
