Suppose we have a set of paired data, and let d=xafter−xbefore . The null hypothesis is H0:μd=0, the alternative hypothesis is Ha:μd≠0, and the population standard deviation σ is not known. Jordan collects a sample of size n=9 and computes d¯=2.2 and sd=3.3What is the value of the test statistic?The probability of obtaining a test statistic greater than Jordan's test statistic is 0.0403. Use this probability to determine the P-value for Jordan's hypothesis test. (Round to three decimal places.)
