Quizplus · Accepted Answer

To find the sum of the ranks for Brand C, first, all the values across all brands need to be ranked together from smallest to largest. Then, the ranks corresponding to Brand C's values are summed. Given the data, Brand C's values when ranked among all others will not sum to a value like 4.78, 22.5, or 23.88, but rather a higher value because there are 15 values in total and Brand C's values are among the higher ones. The correct sum of ranks for Brand C, considering the methodology of ranking, would logically be the highest option provided, which is 58.
