Question: The following data represent the running times of films produced by 2 motion-picture companies. Test the hypothesis that the average running time of films produced

The following data represent the running times of films produced by 2 motion-picture companies. Test the hypothesis that the average running time of films produced by company 2 exceeds the average running time of films produced by company 1 by 10 minutes, against the one sided alternative that the difference is less than 10 minutes. Use a 0.1 level of significance and assume the distributions of times to be approximately normal with unequalvariances.
