16.4 ft - 14.2 ft   = 2.2 ft greater than the mean .....

This is   2.2 / 2.1 = 1.0476 Standar deviations above the mean   

Look at 1.04  (rounded to 1.0 ) in the chart to find that .8413 fraction of sunflowers are LESS than that 16.4 ft    the rest are taller

     1-.8413 = .1587  is the fraction that are TALLER than 16.4 ft      .1587   is equal to 15.87%
