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 955 tenth graders is drawn. Of the students sampled, 812 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

. Step 2 of 2: Suppose a sample of 955 tenth graders is drawn. Of the students sampled, 812 read above the eighth grade level. Using the data, construct the 90% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.

Answer #1

from above:

Step 1 of 2: proportion of tenth graders reading at
or below the eighth grade level. **=0.150**

Step 2 of 2: 90% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level.

**=(0.131 , 0.169)**
