Can someone help me understand how I can solve to find a probability at a certain standard deviation the mean? For example: How would I solve this problem? An explanation would really help!
Find the probability that the flight time will be within one standard deviation of the mean.
μx = 130
σx = 5.7735
Find the probability that the flight time will be within one standard deviation of the mean.
μx = 130
σx = 5.7735
-
(130+/- 1*5.7735) = 124.2265 to 135.7735
the formula is { mean +/- n*SD } for values within n SD from the mean
