The stem-and-leaf display shows only one rating of 92 (stem 9, leaf 2), which is 80 or above. Since there is a total of 25 ratings (3 in the 30s, 10 in the 40s, 6 in the 50s, 5 in the 60s, 2 in the 70s, and 1 in the 90s), the percentage of respondents who rated the quality as 80 or above is 1/25, which is 4%.
