The amusement park officials in question 4.3 wish to add some additional rides aimed toward children...

Suppose they randomly select 400 people and ask their ages. Estimate the proportion of individuals who are below the age of 10 using 97% confidence.

Hi! I keep going round and round with this problem. Do I use 23 as an xbar? If I find a z score how do I equate that to a number of people?
