2. A medical study tests a new cough medicine on 4250 people. It is effective for 3982 people. What is the experimental probabil
Nutka1998 [239]

Answer:

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 = \frac{Number\, of \, Success}{Number\, of \, Trials} Where:

Number of success = 3982 and

Number of trials = 4250. therefore;

Probability \, of \, Success = \frac{3982}{4250} = \frac{1991}{2125}

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

\frac{1991}{2125} = \frac{x}{9000} \rightarrow x \times2125 = 1991 \times 9000\\x = \frac{1991 \times 9000}{2125} = \frac{143352}{17} = 8432\frac{8}{17}

or ≈ 8432 people.
