Ten pregnant women were given an injection of Pitocin to induce labor. Their systolic blood pressures immediately before and after the injection were taken and define the paired differences to be "after - before". The following table shows the summary statistics. Use a 0.05 level of significance. Intermediate Calculations Sample Size 10 d-bar 3.1000 SD 4.2019 The computed value of the test statistic is (final answer to 3 decimal places) Do the data provide sufficient evidence that injection of this drug changes
