John walks 11/16 miles to school each morning. he had walked 2/3 of the distance. how many miles has he walked a. 7/15 b. 13/24 c. 7/18 d. 11/24

Which is the correct excel formula for the 80th percentile of a distribution that is n(475, 33)? =norm. dist(80,475,33,1) =norm. inv(0.80,475,33) =norm. s.inv((80-475)/33)?

Ineed to know the answer right now! !

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?
