To determine the proportion of trees that are infested by
the spotted lantern fly in one region a 99 percent
confidence interval is constructed. It is estimated that
there are 250,000 trees in the region. A random sample
of 500 trees were inspected for spotted lantern fly
activity and 120 of the trees were infested.
Based on this study, which of the following expressions
could be used to create a 99 percent confidence
interval for p, the proportion of trees that are infested?
