F(x)=0 for x<0
=1/3 for 0<=x<=1/2
=1/2 for 1/2<=x<=3/4
=1 for x>=3/4
Determine,for the random variableX,the
(a) upper quartile
(b) lower quartile
(c) propability mass function of X
Re: help me determine quartiles of random variables
Okay, what have you done on this, yourself. Do you know what "upper quartile" and "lower quartile" mean? Do you know how the probability mass function is?
