Construct a normal probability plot of the cycles to failure data in Exercise 6-15. Does it seem reasonable to assume that cycles to failure is normally distributed?

ST 701 Week Four Notes MaLyn Lawhorn September 5, 2017 and September 7, 2017 Independence In words, events A and B are said to be independent if knowledge that B occurred doesn’t change our uncertainty about A. Mathematically, this can be written as if P(B) > 0, then A and B are independent events if P(AjB) = P(A). However, this deﬁnition makes it appear as if direction matters. It sounds as if A being independent from B is not the same as B being independent from A, but this is not the case. A more formal, but less intuitive, mathematical deﬁnition of independence is if A and B are in- dependent events, P(A [ B) = P(A)P(B). In many problems, we can associate the word inde- pendence with the action of multiplying probabilitie
