The height of a sunflower is normally distributed with a mean of 14.2 feet and a standard deviation of 2.15

what is the probability of picking a sunflower that has a height greater than 16.4 feet?

 

Please show all work (how you found z score and final answer)

z score =  [  16.4   - 14.2 ] / [ 2.15 ]  ≈  1.02

 

From  the  z score table this value equates to  ≈ .8461 ≈  84.61%

 

So...the probability of picking a  sunflower > 16.4 ft   =  1  - .8461  ≈  15.39%
