Chi square Test for the Population variance
When we want to test that a random sample has been drawn from a normal population having specified variance then X2 statistic under the null hypothesis for the random sample of n size will be.
X2 = ∑ (X- x¯) / = ns2/
With (n-1) = Degree of freedom
where S2= sample variance
X2= population variance
N= sample size
This value of X2 will be compared with the table value at (n-1) degree of freedom at certain level of significance for accepting or rejecting null hypothesis.
what is the scope of operational research in india ? explain with the job names.
maximize z=3x1+2*2 subject to the constraints x1+x2=4 x1-x2=2 x1.x2=0
The scientific methods is thus based on certain basic postulate which can be stated as under: a. It relies on empirical evidence: b. It utilizes relevant concepts;
Discuss the methodology of operation research
It can be seen from the optimal solution for the foundry problem that two resources, raw material-1 and labor, are exhausted whereas the other two resources, raw materi
NON PARAMETRIC TESTS All practical data follow normal distribution under such situations can estimate the parameters such as mean variance etc ,,, and use the standard
how to solve operation research optimization questions
. A paper mill produces two grades of paper viz., X and Y. Because of raw material restrictions, it cannot produce more than 400 tons of grade X paper and 300 tons of grade Y paper
