Young's modulus is a quantitative measure of stiffness of an elastic material. Suppose that for metal sheets of a particular type, its mean value and standard deviation are 80 GPa and 1.8 GPa, respectively. Suppose the distribution is normal. (Round your answers to four decimal places.)
(a) Calculate P(79 x 81) when n = 25.
(b) How likely is it that the sample mean diameter exceeds 81 when n = 36? You may need to use the appropriate table in the Appendix of Tables to answer this question
