A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

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.

Expert Solution

Step 1

Based on the provided information, the known values are:

Number of success=3982 people.

Number of trials=4250 people.

The probability of success is obtained below:

$\begin{array}{rcl} P r o b a b i l i t y & = & \frac{N u m b e r o f s u c c e s s}{N u m b e r o f t r a i l s} \\ = & \frac{3982}{4250} \\ = & 0.9369 \end{array}$
