Session Unit 3:

                                                                                                        12. Hypothesis Testing

      LOS 12.j: Identify the appropriate TS and interpret the results for a HT concerning 1) the variance of a

      NDP, and 2) the equality of the variances of 2 NDPs based on 2 independent random samples, p299

      Testing the Equality of the Variances of 2 NDPs, Based on 2 Independent Random Samples

      – the F-distributed test statistic

       The F-distribution is right-skewed (too) and is bounded by 0 on the LHS.

       The shape is determined by 2 separate dfs, the numerator, df1, and the denominator, df2.


                                                                          Lets recheck the Chi square one!
