You wish to test the following claim (Ha) at a significance level of a = 0.05. For the context of this problem, d = 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. Hold = 0 Ha: Ha # 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 = 11 subjects. The average difference (classical - silence) is d = 8.2 with a standard deviation of the differences of Sd = 34.2. 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 = The p-value is... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the mean difference between listening to classical music and silence is not equal to 0. O There is not sufficient evidence to warrant rejection of the claim that the mean difference between listening to classical music and silence is not equal to 0. The sample data support the claim that the mean difference between listening to classical music and silence is not equal to 0. O There is not sufficient sample evidence to support the claim that the mean difference between listening to classical music and silence is not equal to 0
