A mountain climber

A mountain climber plans to buy some rope to use as a lifeline. Which of the following would be the better choice? Explain your choice.
Rope A: Mean breaking strength:500lb; the standard deviation of 100lb
Rope B: Mean breaking strength: 500lb; the standard deviation of 10lb

Correct answer:

x = B

Step-by-step explanation:

m1=500 lb s1=100 lb  m2=500 lb s2=10 lb  p1=p(N,m1,s1,x<490)=0.4602 p2=p(N,m2,s2,x<490)=0.1587  p1>p2  x=B

Use the normal distribution table.
