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 2004 tenth graders is drawn. of the students sampled, 1584 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.

0.790

Step-by-step explanation:

Given : The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.

The sample size : n= 2004

The number of students read above the eighth grade level = 1584

Then , the proportion of students read above the eighth grade level is given by :-

Hence, the estimate proportion of tenth graders reading at or below the eighth grade level =0.790

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
