We conduct a survey with questions given below. Identify which questions have a variable that is quantitative? Select all that apply. Are you allowed to use a calculator on the exams? How many questions were on the last homework assignment? What was the score you earned on the last exam? Were the exams open book?

To identify which questions have a variable that is quantitative, we need to understand the nature of quantitative variables. Quantitative variables are those that can be measured and expressed numerically. Let's analyze each question: 1. **Are you allowed to use a calculator on the exams?** - This question is qualitative (categorical) as it can be answered with "yes" or "no." It does not involve a numerical measurement. 2. **How many questions were on the last homework assignment?** - This question is quantitative because it asks for a numerical count of questions. The answer can be expressed as a number (e.g., 10 questions). 3. **What was the score you earned on the last exam?** - This question is also quantitative as it requests a numerical score, which can be expressed as a number (e.g., 85 out of 100). 4. **Were the exams open book?** - Similar to the first question, this is qualitative and can be answered with "yes" or "no." It does not involve a numerical measurement. Based on this analysis, the questions that have a variable that is quantitative are: - **How many questions were on the last homework assignment?** - **What was the score you earned on the last exam?**
