S3: the level of significance and the critical value of the statistic‚ iv. S4: your decision rule and the conclusion reached in not rejecting or rejecting the null hypothesis. When asked to calculate p–value‚ S5‚ relate the p-value to the level of significance in reaching your conclusion. If you use MiniTab to perform the hypothesis test‚

ANOVA Test Paper This week Team C is looking to further our knowledge of hypothesis tests by testing for variances and simultaneously comparing the different means of gasoline to conclude if the populations sampled were equal or not. We will test whether the three sample are from populations with equal variances. This type of testing is called analysis of variance or ANOVA (Lind‚ Marchal‚ & Wathen‚ 2004). The ANOVA test can be conducted with the intent of giving families information on where the

The null hypothesis of this experiment states that there is no effective vaccine for preventing getting the flu while the alternative hypothesis states that there is an effective vaccine for preventing getting the flu. The results obtained from such an experiment should be significant in that they should not be those that purely

A one-sample test‚ also known as a goodness of fit test‚ shows whether the collected data is useful in making a prediction about the population. One sample tests are used when we have a single sample and wish to test the hypothesis that it comes from a specified population. In this case‚ the following questions are encountered: • Is there a difference between observed frequencies and the frequencies we would expect‚ based on some theory? • Is there a difference between observed and expected

included questions covering the whole four weeks. As for statistically analyzing of the exam results‚ the Null Hypothesis was laid down. The latter stated that “There is no statistically difference between the control and the experimental group due to the assessment rich PBL approach”. The statistical analysis of the exam results showed very strong statistical evidence to reject the Null Hypothesis. The experimental group students outperformed significantly the control group students. The results showed
