Sedaia [141]

Answer:

The  confidence interval is  0.304 <  p  < 0.324

Step-by-step explanation:

From the question we are told

      The sample proportion \r p  =  0.314

      The margin of error  is E =  0.01

The confidence interval for  p is mathematically represented as

       \r p -  E  <  p  < \r p + E

=>    0.314 -  0.01  <  p  < 0.314 +  0.01

=>   0.304 <  p  < 0.324
