The level of oxides of nitrogen (NOX) in the exhaust of one light truck model was found to vary amongindividually trucks according to a Normal distribution with mean 1.45 grams per mile driven and standard deviation 0.40grams per mile.(a) What is the 20th percentile for NOX exhaust, rounded to four decimal places? 1.1134(b) Find the interquartile range for the distribution of NOX levels in the exhaust of trucks rounded to four decimal places.0.5396
