Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in acid rain. the acidity of liquids is measured by ph on a scale of 0 to 14. distilled water has ph 7.0, and lower ph values indicate acidity. normal rain is somewhat acidic, so acid rain is sometimes defined as rainfall with a ph below 5.0. if the distribution is really n(5.43,0.54), what proportion of observations would be less than 5.05? (enter your answer rounded to four decimal places.)
