Referring to Q3, suppose that the standard deviation of the random deviation νis 350 psi. a. What is the probability that the observed value of 28-day strength will exceed Assignment 9Student Name: ID: Section:pg. 25000 psi when the value of accelerated strength is 2000? (5 marks)b. Repeat part (a) with 2500 in place of 2000. (3 marks)c. Consider making two independent observations on 28-day strength, the first for anaccelerated strength of 2000 and the second for x = 2500. What is the probability that thesecond observation will exceed the first by more than 1000 psi? (5 marks)d. Let Y1and Y2denote observations on 28-day strength when x =x1and x =x2, respectively. By how much would x2have to exceed x1in order that P(Y2>Y1) =.95
