One-Tailed Test or a Two-Tailed Test - Assignment ExampleIf there were precognition that there was no expected difference, it would be absurd to collect the entropy and do the analysis. In this baptistery scenario, the comparison is between two groups of people in which whizz has received oxygenation medication whereas the other one has not. Jackson (2011) asserts that the use of one tailed analysis is predicated upon a high certainty prior to the data collection that either there is no difference or a difference exists in a certain area of the entire population. In the event that the data analysis ends in showing the world of a difference in the incorrect region, it then becomes automatic that the difference is attributable to random sampling. This setting or assumption is done without giving due thought to the possibility that true difference power be a reflection of the measured or calculated difference (Urdan, 2005). The Probability That Group I Is Different from Group 2 an d the Signifi fuckingce Against the Benchmark of P .05 According to Rasch, Kubinger, and Moder (2011), the null hypothesis can only be rejected when the t-static from tables is less or greater than t critical two-tail value gotten later on computation. Therefore, if the test statistic is less than -2.12 or greater than 2.12, the null hypothesis will be rejected and the pick hypothesis adopted instead. The test statistic is 0.899, which falls into the rejection region, so the null hypothesis is not rejected, which states that there is no difference between the means from the two samples.
