Hypotheses and summary sample statistics are given for a test for difference in means using paired data. Assume that the conditions are met and the underlying distribution is approximately normal. TestH0:d=0vsHa>0when the sample hasxd=1.5withsd=7.1andnd=20.

Find the value of thet-test statistic and then use thet-distribution to find thep-value. Round your answers to three decimal places. test statistic =_______

p-value = _________
