15. (15 points) 100 people participate in a quick calculation test, with a total of 10 questions. The number of people who answered each question correctly is shown in the table below:
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|}
\hline Question Number & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\
\hline \begin{tabular}{l} 
Correct \\
Answers
\end{tabular} & 93 & 90 & 86 & 91 & 80 & 83 & 72 & 75 & 78 & 59 \\
\hline
\end{tabular}

Rule: Answering 6 or more questions correctly is considered passing. Based on the table above, calculate the minimum number of people who passed.
【Analysis】First determine the total number of wrong answers, those who fail must have at least 5 wrong answers, which will lead to the result.
【Solution】Solution: The total number of wrong answers for each question is $7+10+14+9+20+17+28+25+22+41=193$,
For each person who fails, they must have at least 5 wrong answers, $193 \div 5=38 \cdots 3$,
Therefore, at most 38 people can fail, and at least 62 people pass.
To show that this is possible, note that 41 is exactly 3 more than 38,
So these 38 people all got the 10th question wrong, and the remaining wrong answers are evenly distributed among the other 9 questions.
Answer: At least 62 people pass.
