Question

An environmentalist wants to find out the fraction of oil tankers that have spills each month. Step 2 of 2 : Suppose a sample of 451 tankers is drawn. Of these ships, 321 did not have spills. Using the data, construct the 95% confidence interval for the population proportion of oil tankers that have spills each month. Round your answers to three decimal places.

Step 1

First, determine the number of tankers that had spills. Since 321 tankers did not have spills, the remaining tankers that had spills is 451 (total tankers) - 321 (tankers without spills) = 130 tankers with spills. Next, calculate the sample proportion (p̂) of Show more…
