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" is %. therefore, adding the two together, the percentage of patrons below 54" and who may not use this ride is %.
