pls show work with correct answer choice

Question # 2 (3.5 Marks) Measurements on tolerances of a manufactured item refer to six bimonthly data, i- 1, 2, ..., 6 of random values (RVS) with corresponding frequency of occurrence (n). Relevant quality control assessments are done at independent locations, Site X and Site Y and pertinent details are listed below.
