Best ResponseYou've already chosen the best response.2Do you have access to a normal distribution table or graph? You will probably either need that or have the percentages for different standard deviations memorized...

Best ResponseYou've already chosen the best response.2Hmm... seems off somewhat, since the question wants the percentage taller than the average basket ball player. Almost everyone is taller? :)

Best ResponseYou've already chosen the best response.2Since we know that to the left is 99.865% it follows that the remaining area to the right adds up to 100%. This means that the area we seek is 100  99.865 = 0.135%
