We wish to estimate what percent of adult residents in a certain county are parents. Out of 500 adult residents sampled, 175 had kids. Based on this, construct a 99% confidence interval for the proportion p of adult residents who are parents in this county. Express your answer in tri-inequality form. Give your answers as decimals, to three places.

The 99% confidence interval  is  

Step-by-step explanation:

From the question we are told that

     The sample size is  

      The the number that are parents  x =  175

The  proportion of parents is  mathematically represented as

substituting values

The  level of confidence is given as 99%  which implies that the level of significance is  

       1%

The critical value for this level of significance is obtained from the table of critical value as

Generally the margin of error is mathematically evaluated as

substituting values

Generally the 99% confidence interval is mathematically represented as

substituting values

do you have a picture of the table

inverse property is the answer
