Answer to Problem 118AYU
The interval of possible test scores of the people in the top
Explanation of Solution
Given information:
The average score of intelligence test is
Calculation:
Assume the possible test score to be
The highest possible score is greater than
Express it in inequality.
Solve the inequality.
So the value should be greater than
The range can be written as
Therefore, the interval of possible test scores of the people in the top
