An environmentalist wants to find out the fraction of oiltankers that have spills each month.
Step 1 of 2:
Suppose a sample of 292 tankers is drawn. Of these ships, 58 hadspills. Using the data, estimate the proportion of oil tankers thathad spills. Enter your answer as a fraction or a decimal numberrounded to three decimal places.
Step 2 of 2:
Suppose a sample of 292 tankers is drawn. Of these ships, 58 hadspills. Using the data, construct the 80% confidence interval forthe population proportion of oil tankers that have spills eachmonth. Round your answers to three decimal places.
