Answer #1

Find the number z such that proportion of observations that are less than z in a standard normal distribution is 0.6. ?

P( z < 0.253) =0.6

Required z= 0.253

find the number z such that 15% of all observations from a standard normal distribution are greater than z ?

P( z > 1.036 ) =0.15

Required z= 1.036
