Question

if Ms. sanchez has 32 students in her class, about how many students earned a grade of 80% or higher? about how many earned more than 90%? explain how you know.

Answer 1

Without specific data for Ms. Sanchez's class, we estimate about 10 students earned a grade of 80% or higher and 2 or 3 students earned more than 90%, based on typical or example percentile distributions.

Step-by-step explanation:

To determine how many students earned a grade of 80% or higher, and how many earned more than 90%, we can use percentile information if it's given. Without specific data from Ms. Sanchez's class, we have to rely on typical grade distributions or provided examples.

Considering an example where 70% of students score 16 or fewer correct answers, and 30% score 16 or more, we can apply similar reasoning. If 70% of Ms. Sanchez's 32 students scored below a certain grade, then the remaining 30% scored above it. This would imply that about 10 students (32 students * 0.30) scored 80% or higher.

For scores above 90%, if we have an example where 7.5% of students score in this range, we would estimate that about 2 or 3 students (32 students * 0.075) in Ms. Sanchez's class achieved this mark.

Ultimately, without the exact distribution of grades in Ms. Sanchez's class, these are just estimations based on other examples.
