answer plsssss

H1-H₂ = do I || V= The following data represent the running times of films produced by two motion-picture companies. 103 94 110 82 97 (F1-F₂)-do /3₁/1₁ +8²/1₂ (s/n₁ + s/n₂) + Company Time (minutes) 87 98 123 92 175 88 118 Test the hypothesis that μ = μ against μ, using 0.01 level of significance. Assume that the running-time differences are approximately normally distributed with unequal variances. The mean running time is the same. (8/₁)² (8/1₂) n₁-1 ng-1 01 02 and unknown
