Novanordic pharmaceuticals is racing to find a treatment for Covid-19.  They are currently doing clinical trials to test the efficacy of their vaccine.  In their studies, they set up 2 different groups; Group 1, consisting of 35 subjects will receive a placebo.  Group 2 consisting of 35 subjects will receive the experimental vaccine.    Six months later, they determined that Group 1 (placebo) hand an average infection 86 while Group 2 (experimental vaccine) had an average infection of 94.    Given the variance for Group 1 is s2=106 and the variance for Group 2 is s2=107, calculate the appropriate statistic.
