You wish to test the following claim (HaHa) at a significance level of α=0.02α=0.02. For the context of this problem, μd=μ2−μ1μd=μ2-μ1 where the first data set represents a pre-test and the second data set represents a post-test.

      Ho:μd=0Ho:μd=0
      Ha:μd<0Ha: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:

pre-test post-test
51.9 69.5
52.9 4.9
59.4 29.8
56.8 -33.5
54.9 45.9
58.8 -10.6
52.3 98.1
58.2 4.9
55.8 130.3
53 77.5
52.5 51.2
59 46.7
50.8 52.9
51.5 -10.1
48.4 23.6



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 =
