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 75 gpa and 2.1 gpa, respectively. suppose the distribution is normal. (round your answers to four decimal ) calculate p(74 ? x ? 76) when n = 25.(b)how likely is it that the sample mean diameter exceeds 76 when n = 49?

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
