You wish to test the following claim (Ha) at a significance level of a = 0.10. For the context of this problem, d = new - old where the first data set represents the rating for an old product and the second data set represents the scores for the new product. Ho: Ma = 0 Ha: Hd > 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: old new 48.9 58.3 65.9 71.5 58.5 58.7 54.6 67.3 52.3 73.2 49.1 63.2 54.8 73.9 68.2 60.2 68.2 90.9 What is the test statistic for this sample? (Report answer accurate to three decimal places.) t = The p-value is ... This p-value 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 on average, the new score for the product is greater than the old score.. There is not sufficient evidence to warrant rejection of the claim that on average, the new score for the product is greater than the old score.. O There is sufficient evidence in the sample data to support the claim that on average, the new score for the product is greater than the old score.. There is not sufficient evidence in the sample data to support the claim that on average, the new score for the product is greater than the old score
