Assume that the variable under consideration has a density curve. Answer parts (a) through (c).

10(a) The area under the density curve that lies to the right of 16 is 0.359.

What percentage of all possible observations of the variable exceed 16? %

What percentage of all possible observations of the variable are at most 16? %

10(b) The area under the density curve that lies between 15 and 19 is 0.628.

What percentage of all possible observations of the variable are either less than 15 or greater than 19? %

10(c) It is given that 32.1% of all possible observations of the variable are less than 17.
