Question

a survey found that womens heights are nomrally distributed with mean 62.2 in. and standard deviation 2.5 in the survey also found that mens heights are normally distributed with a mean 68.5 and standard deviation 2.8 
a) Most of the live characters at an amusement park have height requirements with a minimum of 4ft 9in and a max of 6ft 2in find the percentage of women meeting the height requirement

andijo76 · Answer

b) find the percentage of men meeting the height requirement
c) if the height requirements are changed to exclude only the tallest 5% of men and the shortest 5% of women what are the new height requirements 
the new height requirements are at least___in and at most___in

anonymous · Answer

Use the cumulative normal distribution probability tables with

z-scores: upper limit z=(limit - mean)/s.d.       s.d = standard deviation
fraction of normal above this z

lower limit    z =(limit -mean)/ s.d  and fraction of normal below this z. 

continue to apply the cumulative normal probability tabulated values for the next two questions, as wel, converting to and from z = (value - mean)/s.d.
