The length of sweetpea flower stems are normally distributed with mean 18.2 cm and standard deviation 2.3 cm. (a) Find the probability that the length of a flower stem is between 16 cm and 20 cm. Answer: 0.6139 *I found it and, it's correct*. (b) 12% of the flower stems are longer than h cm. 20% of the flower stems are shorter than k cm. Find h and k. *Need Help*

h = 20.9 k = 16.26 you have to use a standard normal table or lookup software if 12% are longer, then 88% are shorter...look up .88 find Z-value Z = (h-18.2)/2.3 For k do same thing ...look up 0.2 find Z-value Z = (k-18.2)/2.3
