In 2002, the median pH level of the rain in a national park was 5.20. A biologist thinks that the acidity of rain has decreased since then. (This would mean that the pH level of the rain has increased.) She obtains a random sample of 19 rain dates in 2008 and obtains the accompanying data. Determine the P-value of the hypothesis test performed in the statement. Click the button to see the data table. Click the button to see the method of calculation of the P-value. The P-value is (Round to four decimal places as needed.)
