If X has a normal distribution with mean 27.5, and standard deviation 9.2, find the "c" such that P(X>c) =0.55
Need step by step on how to solve using EXCEL
c=26.64.......................by using Excel =NORMINV(1-0.55,27.5,9.2)
We have use here , 1-0.55 because area under standard normal curve in right tail.
