Earthworms of the species Lumbricus terrestris often surface after a large rain storm. It is unclear why they surface in such abundance after large amounts of rain. The lengths of this species of earthworm are normally distributed with an average length of 180 mm with a standard deviation of 15.5 mm. What length would we expect to find at the 30th percentile? (A) 22.54 (B) 78.89 (C) 109.89 (D) 171.87 (E) 188.13
