Are my answers right for the first data set?
To determine if your answers are correct for the first data set, you would need to compare them with the expected or correct answers.
If you have access to the correct answers, you can compare each of your answers to the expected answers one by one. If they match, then your answers are correct for the first data set. However, if there are any discrepancies, then you would need to review your work and identify any mistakes that might have been made.
If you do not have access to the correct answers, you can seek assistance from your teacher, professor, or a knowledgeable peer who can help review your answers and provide feedback.
It is important to note that without the specific questions and answers, I cannot directly determine if your answers are correct. Please provide more information or details about the questions and answers, and I will do my best to guide you in evaluating their accuracy.
