klemol [59]

Answer:

The conclusion about p using an absolute value inequality is  

   0.325  <  p <  0.375

Step-by-step explanation:

   The  sample proportion is  \r p =  0.35

    The  margin of error is  E =  0.025

The confidence interval is mathematically represented as

           \r p  -E  <  p <  \r p +E

=>        0.35 - 0.025 <  p <  0.35 + 0.025

=>      0.325  <  p <  0.375
