For example, the first question talks about something being normally distributed, then requires that a maximum dependent upon that distribution be calculated. Since a normal distribution has no maximum (just lower and lower probabilities for larger and larger deviations) the only way to obtain a maximum is to set a threshold for the number of deviations to be considered. But there is no absolute rule for what one might consider the correct number of deviations to assume in such a case - depending on circumstances, 2, 3 or 6 sigma might be used. antisaviour11th Apr 2009, 20:17http://img152.imageshack.us/img152/7571/98517955.png No further reference is required as all of the information needed is given in the question. antisaviour12th Apr 2009, 09:05Airport planners or consultants please help with the above questions. Thanks. Cyrano12th Apr 2009, 19:10Antisaviour: you've joined PPRuNe just in order to ask us to do your homework for you?? :ugh: Not cool. If there was a specific point you didn't understand, it would be reasonable to ask people here if they could explain it for you. But just asking someone to do your entire assignment? Does the term "plagiarism" mean anything to you? Jetdriver13th Apr 2009, 00:46This forum is aimed at questions for professional pilots.
