The elongation of a steel bar under a particular load has been established to be normally distributed with a mean of 0.05 inch and 0 =0.01 inch. 11. (4 points) Find the probability that the elongation is between 0.025 and 0.065 inches. 12. (4 points) What is the 95th percentile of elongation? 13. (4 points) If we sampled 10 of the steel bars at random, what is the probability the elongation of 8 of them would exceed the 95th percentile
