(a) Find the probability that the sample contains 800 new jobs provided by small businesses.
---
Binomial Problem with n = 1000 and p = 0.75
----
P(x = 800) = 1000C800*0.75^800*0.25^200 = 0.00002869
==========================
(b) What is the most likely number of new jobs to be provided by small businesses?
mean = np = 1000*0.75 = 750
==========================
(c) Find and interpret the mean.
Same answer as "b".
