Hi Can someone help me on the following questions: Determine the value of z in the following case: Pr(-z<Z<z)=0.954 I done InvNorm(0.954,0,1) but this is incorrect Find the quartiles of the standard normal distribution? P.S

first find the it will be equal to so find z according to that value from the data sheet

because normally on datasheets, is given, so after halving 0.954 you'll get . In order to get the above value you should add 0.5 (because the graph is symmetrical around P(z) axis)
How would i find the quartiles of the standard normal distribution? i know that there it is split into three sections, but how do i calculate the percentages
