Investigators selected an srs of 200 high school seniors from a population of 2000 for a survey of television-viewing habits, with an overall response rate of 75%. by checking school records, they were able to find the grade point average for the nonrespondents, and classify the sample accordingly:

They were able to find the grade point averaga for the nonrespondents, and classify the sample by the average result of the survey conducted with 10% of the population. The grade achieved corresponded to 75% of the ranking, exceeding the average.

Step-by-step explanation:

200 represents 10% of the 2000 population, doing the research and averaging the answers given by the 200 people yielded the final result.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
