Let X ~Normal(200, 60). Use Excel (Use the functions NORMDIST or NORMSINV, and fill in the dialogue box appropriately) to find the following.
k such that P(X>k)=0.01?
This is the only one giving me problems I use the normdist formula in excel and i enter the mean std deviation and the value (True/False) but I don't see how I can solve for a specific value, unless i just keep doing trial and error and i know this is not the right way to go about it.
thanks for any help.
