The thundering herd, an amusement park ride, is not open to patrons less than 54" tall. if the mean height of park patrons is 68" with a standard deviation of 12 inches, what percent of the patrons will not be able to use this ride?

the z for 54" =
(the negative means 54" is less than the mean of 68." do not enter a negative percent.)

the percentage for the above z is %

this is the percentage of patrons between 54" and 68". the percentage for all patrons above 68" is %
(this corresponds to z = +4.)

so the percentage of patrons above 54" %
