On the basis of extensive tests, the yield point of a particular type of mild steel-reinforcing bar is known to be normally distributed with s = 100. the composition of the bar has been slightly modified, but the modification is not believed to have affected either the normality or the value of s.(a) assuming this to be the case, if a sample of 64 modified bars resulted in a sample average yield point of 8469 lb, compute a 90% ci for the true average yield point of the modified bar. (round your answers to one decimal ) how would you modify the interval in part (a) to obtain a confidence level of 96%? (round your answer to two decimal places.)
