I need help with questions A, B & C

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? null hypothesis tells that there is
no difference in sample means or proportion
b) Describe a Type I error in context along with the consequence.
c) Describe a Type Il 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 ripcord malfunctions.
Does this guard against Type I or Type II errors? Explain.
f) Suppose you went skydiving and pull the ripcord and it does not function.
You have time to pull it again or pull the back-up but not both.
What would you do?
