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 70 GPa and 2.2 GPa, respectively. Suppose the distribution is normal. (Round your answers to fourdecimal places.)In USE SALT(a) Calculate P(69 < X< 71) when n = 25.(b) How likely is it that the sample mean diameter exceeds 71 when n = 36?You may need to use the appropriate table in the Appendix of Tables to answer this question.

We know that X~N(mu,sigma^2) mu=70 ,sigma =2.2 Z-score =(x-mu)/sigma
