MCQs
If X and Y are random variables, then is equal to:
Ideally the width The __________:
of confidence interval should be
F-distribution always ranges from:
Chi- Square distribution is continuous distribution ranging from:
Which one is the correct formula for finding desired sample size
E(4X + 5) =__________
Short question.
Write down the any two properties of probability density function.(2)
random sample of size n is drawn from normal population with mean 5 and variance .
If s=15, =14 and t=3, what is values of n? (5)
the Poisson distribution P(x) = the mean value is :
one question is from the probability distribution function
f(x)= marks
5)
find the value of A.
brother these question are in mind in this time. Only one long question is attempt density probability function which is given in the end.
