When designing a study to determine this population proportion, what is the minimum number of drivers you would need to survey to be 95% confident that the population proportion is estimated to within 0.02

The sample size is

Step-by-step explanation:

From the question we are told that

    The margin of error is  

From the question we are told the confidence level is  95% , hence the level of significance is    

=>  

Generally from the normal distribution table the critical value  of   is  

Generally we will assume the sample proportion to be  

Generally the sample size is mathematically represented as

=>

=>
