You wish to test the following claim (Ha) at a significance level of α = 0.02. For the context of this problem, d = PostTest - PreTest where the first data set represents a pre-test and the second data set represents a post-test. (Each row represents the pre and post test scores for an individual. Be careful when you enter your data and specify what your #₁ and ₂ are so that the differences are computed correctly.) Ho: Pd=0 Ha: pd #0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation.

Question

For the homework what is Test statistic and P value?

You wish to test the following claim (Ha) at a significance level of a = 0.02. For the context of this problem, d = PostTest - PreTest where the first data set represents a pre-test and the second data set represents a post-test. (Each row represents the pre and post test scores for an individual. Be careful when you enter your data and specify what your #₁ and 2 are so that the differences are computed correctly.) Ho: Md=0 Ha : μd #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: post-test pre-test 42.6 35.9 35.5 42.3 38.5 47.1 35.9 48.2 50.4 50.4 35.5 48.8 45.1 36.9 35.5 60.3 30.9 38.2 36.5 36.2 67.9 39.3 60.5 45.7 56.1 39.4 42.5 56.4 24.5 27.8 What is the test statistic for this sample? test statistic = (Report answer accurate to 4 decimal places.) What is the p-value for this sample? p-value = (Report answer accurate to 4 decimal places.)
