Expert Solution
Step 1
The proportion of favorable outcomes can be calculated by dividing the number of favorable outcomes with the total number of outcomes.
The estimation of the population proportion on the basis of the sample proportion involves some error. This error is the sampling error. It can be given by the difference between the sample proportion and the population proportion.
