The number of tankers that had spills is 281 - 228 = 53.
Therefore, the fraction of oil tankers that had spills is 53/281 ≈ 0.188.
An environmentalist wants to find out the fraction of oil tankers that have spills each month.
Step 1 of 2 : Suppose a sample of 281
tankers is drawn. Of these ships, 228
did not have spills. Using the data, estimate the proportion of oil tankers that had spills. Enter your answer as a fraction or a decimal number rounded to three decimal places.
