Q . Ten athletes ran a 400 metres race at ocean level and at a later meeting ran other 400 metres race at altitude . Their time in seconds were as followsRunner Seal-level elevatedA 48 .5 50 .6B 47 .6 47 .3C 49 .2 50 .8D 50 .7 52 .3E 48 .8 47 .7F 51 .1 55 .3G 49 48 .9H 48 .1 49 .9I 50 .7 54 .8J 47 .6 48 .5 Use a subject parametric procedure to test the hypothesis that the athlete s performances be not affected by altitudeThe parametric procedure view as will be t-test : Paired Two Sample for MeansStep 1 : The Null and Alternate HypothesesSince we have no reason to be interested in directionality , we will choose a two-tailed test using these hypotheses :Step 2 : The finish master over -2 .262 .

The stopping point practice isif t 2 .262 The decision rule is shown in below figure 1Figure 1 : Decision ruleStep 3 : Calculate the Test StatisticThe mean and standard deviation ar calculated in the usual way , as shown in put off 1 , so the test statistic is Table 1Runner Seal-level Altitude DifferenceA 48 .5 50 .6 -2 .1B 47 .6 47 .3 0 .3C 49 .2 50 .8 -1 .6D 50 .7 52 .3 -1 .6E 48 .8 47 .7 1 .1F 51 .1 55 .3 -4 .2G 49 48 .9 0 .1H 48...If you lack to get a full essay, order it on our website: OrderCustomPaper.com
