3.3 INFERENCE FOR POPULATION VARIANCE 1) We can calculate the estimated population variancewith 2) also note that this is true: 2 *where X is representative of the chi square distribution with n-1 degrees of freedom 3.3.1 CONFIDENCE INTERVAL 3.3.2 HYPOTHESIS TEST 2 1) To test something dealing with σ we use test statistic: where the null hypothesis is still rejected when p-value
