Q18. Use the NHST method when answering this question. You have discovered what appears to be a new form of inch-worm. The observed mean length for the group of 392 specimens collected is 3.25cm, with a standard deviation of 0.8. If the population mean length for inch-worms is 2.54cm, does your data support the claim that you have discovered a new species? (9 marks) Q19. Use the same information provided in Q18 (above). Would your answer change (and how) if we know that the population standard deviation for inch-worms is 0.76? (4 marks)
