1. **State the problem:** We are given the number of students who scored at least certain percentages and need to find how many scored at least 80% but less than 90%. 2. **Given data:** - At least 95%: 5 students - At least 90%: 13 students - At least 85%: 27 students - At least 80%: 50 students 3. **Understand the problem:** "At least 80%" means all students scoring 80% or above, which is 50 students. "At least 90%" means all students scoring 90% or above, which is 13 students. 4. **Find the number of students scoring between 80% and less than 90%:** This is the difference between students scoring at least 80% and those scoring at least 90%: $$\text{Number} = 50 - 13 = 37$$ 5. **Answer:** 37 students scored at least 80% but less than 90%. **Final answer: (D) 37**
