One study found a significant correlation of .40 between language skills and the size of the big toe in a sample of children. However, it turns out that age is also related to both big toe size (a correlation of .55) and language skills (a correlation of .65). (a)  Find the correlation of language skills and size of the big toe in children once the effects of age have been removed. (b)  What does this tell us about the original correlation found between language skills and big toe size?
