Question 1 A parachutist has made thousands of successful jumps. His assumption is that when he pulls the ripcord, the parachute will open. a) What are the null and alternative hypothesis? b) Describe a Type I error in context along with the consequence. c) Describe a Type II error in context along with the consequence. d) Which is a more serious error in this context? Justify your answer. e) Most parachutes have a backup in case the rip cord malfunctions. Does this guard against Type I or Type II errors? Explain. f) Suppose you went skydiving and pull the rip cord and it does not function. You have time to pull it again or pull the back-up but not both. What would you do?
