Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  582

   The number of teenagers at the wheel is k = 91

Generally the sample proportion is mathematically represented as

=>      

=>      

From the question we are told the confidence level is  90% , hence the level of significance is    

=>  

Generally from the normal distribution table the critical value  of   is  

Generally the margin of error is mathematically represented as  

=>  

=>  

Generally 95% confidence interval is mathematically represented as  

=>  

=>
