We wish to estimate what percent of adult residents in a certain county are parents. Out of 300 adult residents sampled, 45 had kids. Based on this, construct a 99% confidence interval for the proportion p of adult residents who are parents in this county.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
