21. Complete the following in Python. An environmentalist wants to find out the fraction of oil tankers that have spills cach month Step 1. Suppose a sample of 474 tankers is drawn of these ships. 156 had spills. Using the data, estimate the proportion of oil tankers that had spills. (Write your answer as a fraction or a decimal number rounded to 3 decimal places) [Continued on next page...) Step 2. Suppose a sample of 474 tankers is drawn. Of these ships. 156 had 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 3 decimal places) Lower Bound Upper Bound
