Suppose 32% of UNF students pull at least one all-nighter during finals week. A random sample of 14 UNF students was selected. (Round to 3 decimal places.)   a. Find the probability that between 4 and 6 (inclusive – meaning you include the 4 and 6 in your calculations) of these students pulled at least one all-nighter during finals week. [a] b. Find the expected number of UNF students who pull at least one all-nighter during finals week. [b]

Suppose 18% of UNF students pull at least one all-nighter during finals week. A random sample of 20 UNF students was selected. (Round to 3 decimal places.)   a. Find the probability that between 2 and 4 (inclusive – meaning you include the 2 and 4 in your calculations) of these students pulled at least one all-nighter during finals week. [a] b. Find the expected number of UNF students who pull at least one all-nighter during finals week. [b]
