To find the percentage of respondents that rated overall television quality with a rating of 50 or below, we must look at the stem-and-leaf display and count the number of values that fall within the range of 00-50. From the stem-and-leaf, we can see that there are a total of 25 values, and 11 of those values fall within the range of 00-50. Therefore, the percentage is (11/25)*100, which is equal to 44%. So, the correct answer is C.
