The percentage of high - school teenagers for whom doing well in school is the most important problem is 11%.

Step3: Calculate the number

We calculate 11% of 19,006,721. Using the formula \(n = p\times N\), where \(p=\frac{11}{100}=0.11\) and \(N = 19006721\). So \(n=0.11\times19006721 = 2090739.31\approx1900000\) (rounding to the nearest hundred - thousand as an estimate). Among the options, the closest value to our estimate is 1,900,000.
