What percentage of subway riders must re-swipe the card

Reference no: EM13210342

Passengers using New York's MetroCard system must swipe the card at a rate between 10 and 40 inches per second, or else the card must be re-swiped through the card reader. Research shows that actual swipe rates by subway riders are uniformly distributed between 5 and 50 inches per second.

Determine the following:

(a) Mean swipe rate
(b) Standard deviation of the swipe rate
(c-1) 1st Quartile
(c-2) 3rd Quartile

(d) What percentage of subway riders must re-swipe the card because they were outside the acceptable range?
