When I enter X XXXX the calculator linked above XXXX it set XX one-sided, I XX told that XXXXX XX a XX.XXX% XXXXXX of XXX value in XXX distribution XXXXX less than or equal to X XXXXXXXX XXXXXXXXXX XXXX the XXXX. XX other XXXXX, XX I XXXXXXXX chose a value XXXX XXX XXXXXXXXXXXX, there is a 97.725% it's Z-Score XXXX XX XXXX XXXX or equal to 2.
The calculator also tells me that XXXXX XX a 2.XXX% chance XX XXX value in XXX distribution XXXXX greater XXXX X Standard XXXXXXXXXX XXXX the XXXX XXXXX makes XXXXX XXXX XXXXXXXX XXXX 97.725 + 2.275 = XXX.
