Environmental engineers are using data collected by weather data centers to learn how climate affects the sea ice. Of 503 ice melt ponds studied in a certain region, 96 were classified as having "first-year ice". The researchers estimated that about 19% of melt ponds in the region have first-year ice. Estimate, with 90% confidence, the percentage of all ice-melt ponds in the region that have first-year ice. Give a practical interpretation of the results. Construct a 90% confidence interval around the sample proportion of ice melt ponds with first-year ice. (Round to four decimal places as needed.)
