2. A medical study tests a new cough medicine on 4250 people. It is effective for 3982 people. What is the experimental probability that the medicine is effective? For a group of 9000 people, predict the approximate number of people for whom the medicine will be effective.

For a 9000 people, the approximate number of people for whom the medicine will be effect is 8432 people

Step-by-step explanation:

Here we have probability is given by

Probability = Where:

Number of success = 3982 and

Number of trials = 4250. therefore;

Therefore, when the medicine is used on 9000 people, the approximate number of people for whom the medicine will be effect is given by;

or ≈ 8432 people.
