Step 1
Let be the random sample of size n from the normal population with mean and variance then, to test whether the population variance is equal to the specified variance or not, the testing procedure is given by:
Null hypothesis: Ho:
Alternative hypothesis: Ha:
Test statistics:
where
- s2 is sample variance.
- n is sample size.
- follows chi-square distribution with (n-1) degree of freedom.
Then comparing calculated value with the tabulated value at given level of significance and degree of freedom, we will accept or reject the hypothesis.
- if calculated value is greater than the tabulated value at given level of significance and degree of freedom, we can not accept the hypothesis.
- if calculated value is less than the tabulated value at given level of significance and degree of freedom, we can not reject the hypothesis.
