Question: 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

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 p < p + E or p > p E, where the margin of error E is modified by replacing za>2 with za. (Instead of dividing a 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.
