Question

the state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. step 1 of 2 : suppose a sample of 2552 tenth graders is drawn. of the students sampled, 2119 read above the eighth grade level. using the data, estimate the proportion of tenth graders reading at or below the eighth grade level. enter your answer as a fraction or a decimal number rounded to three decimal places.

Answer 1

The proportion of tenth graders reading at or below the eighth grade level can be estimated as:

(number of students reading at or below eighth grade level) / (total number of students sampled)

Since we are given that 2119 students read above the eighth grade level, the number of students reading at or below the eighth grade level is:

2552 - 2119 = 433

Therefore, the estimated proportion of tenth graders reading at or below the eighth grade level is:

433 / 2552 ≈ 0.170 (rounded to three decimal places)

So the answer is 0.170, which represents the proportion of tenth graders reading at or below the eighth grade level.
