You wish to test the following claim (HaHa) at a significance level of α=0.01. For the context of this problem, d=classical−silenced=classical-silence where the first data set represents the number of seconds it takes to complete a task when classical music is being played and the second data set represents a number of seconds it takes to complete the same task in silence by the same person. Ho:μd=0 Ha:μd>0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain classical and silence times from a sample of n=25 subjects. The average difference (classical - silence) is d=2.6 with a standard deviation of the differences of sd=26.1 What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =
