Unifrom distribution ?
a continuous random variable X is uniformly distributed in the interval 2<=X<=6 and can take no other value
1.what is the probability density function ?
2.find mean and standard deviation of X ?
3.obtain distribution function of X?
yr obviously i can answer for first two question ...
1.for a uniform function
PDF is f(x)=1/(b-a)====>f(x)=1/4
2.mean=a+b/2=2+6/2=4;
SD= (b-a)^2/12=4^2/12=16/12=4/3
but i have no idea how to do the third part ...please can anybody help me out...what is distribution function of X ...Not only the answer ...theory behind it ...then i may be able to get the answer for my self
