Chapter 7, Problem 43BB(choose chapter or problem)
OneSided Confidence Interval A one-sided claim about a population proportion is a claim that the proportion is less than (or greater than) some specific value. Such a claim can be formally addressed using a one-sided confidence interval for p, which can be expressed as \(\mathrm{p < p\ ^\wedge + E}\) or \(\mathrm{p > p\ ^\wedge - E}\) , where the margin of error E is modified by replacing \(\mathrm{z\ \alpha\ /\ 2}\) with \(\mathrm{z\ \alpha}\) . (Instead of dividing α between two tails of the standard normal distribution, put all of it in one tail.) Repeat part (c) of Example 3 by constructing an appropriate one-sided 95% confidence interval.
