     Find the following percentiles for the standard normal distribution. Interpolate where appropriate,91st  9th  75th  25th 6th 
  
  Solution
in a standard normal distribution mean = 0 and standard deviation = 1
so
a)
91 st will be 1.34
b)
9th will be -1.34
c)
75th will be 0.6
d)
25th will be -0.6
e)
6th woill be -1.55
