The number of hours they spent managing their teams during the first week of the 2013 was also recorded, with the accompanying results. Perform a hypothesis test using 0.01 to determine if the players spent more time managing their teams in 2013 than 2012. EE Click the icon to view the yearly recorded times. E Click the icon to view a table of critical values for the Wilcoxon signed-rank test. Determine the null and alternative hypotheses. Ho: Players Y time on their teams in 2013 than in 2012. H1: Players time on their teams in 2013 than in 2012. Determine the test statistic, T (Type an integer or a decimal.) What is the critical value for the test, Ta? Identify the decision rule for this test. v reject Ho State the conclusion of the test. Ho. There is evidence to conclude that players in 2013 in 2012.Explanation / Answer
HO: les then or equal to
Ha: greater
T==2.7786
if T>=2.7636 reject Ho
reject Ho / there is suffiicient.................in 2013 more time......then in 2012
