a sample of 500 high schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of ±45.2. if there are 3250 high schools in the state, what is the estimated number of students per grade level? between and students

Answer

Explanation:

Step1: Calculate the lower - bound

Subtract the margin of error from the average. $178.6 - 45.2=133.4$

Step2: Calculate the upper - bound

Add the margin of error to the average. $178.6 + 45.2 = 223.8$

Answer:

between $133.4$ and $223.8$ students
