Parts b, c, and d only please. An article considered regressing y = 28-day standard-cured strength (psi) against x = accelerated strength (psi). Supposethe equation of the true regression line is y = 1900 + 1.4x, and that the standard deviation of the random deviation e is350 psi.A USE SALT(a) What is the probability that the observed value of 28-day strength will exceed 5000 psi when the value of acceleratedstrength is 2000? (Round your answer to four decimal places.)0.1949(b) What is the probability that the observed value of 28-day strength vwill exceed 5000 psi when the value of acceleratedstrength is 2400? (Round your answer to four decimal places.)0.0012(c) Consider making two independent observations on 28-day strength, the first for an accelerated strength of 2000 andthe second for x = 2400. What is the probability that the second observation will exceed the first by more than1000 psi? (Round your answer to four decimal places.)0.1681(d) Let Y, and Y, denote observations on 28-day strength when x = x, and x = x,, respectively. By how much would x,in order that P(Y, > Y,) = 0.95? (Round your answer to two decimal places.)have to exceed x,826.33
