2. One of the purposes of an investigation by Porcellini et al. was to investigate the effect on CD4 T cell count of administration of intermittent interleukin (IL-2) in addition to highly active antiretroviral therapy (HAART). The following table shows the CD4 I cell count at baseline and then again after 12 months of HAART therapy with IL-2. Do the data show, at the 0.05 level, a significant change in CD4 T cell count?
