You can access the applet for any of the distributions at http://www.socr.ucla.edu under the '''Distributions''' tab. Use SOCR to graph the following distributions and answer the questions below. Also, comment on the shape of each one of these distributions.

===Binomial Distribution Activity ===

==== 1 ====
X~Binom(10,.5)
Find: P(x = 3),E(X), sd(X) and verify them with the formulas discussed in class.
==== 2 ====
X~Binom(10,.1)
Find and verify:

P(1 <= x <= 3)

==== 3 ====
X~Binom(10,.9)
Find and verify:

P(5 < x < 8)

P(x < 8)

P(x <= 7)

P(x >= 9)

====4==== X~Binom(30,.1)

Find and verify:

P(x > 2)

===Distribution Comparison===

Graph and comment on the shape of binomial with n = 20,p = 0.1 and n = 20,p = 0.9
(take a snapshot of each). Now, keep n = 20 but change p = 0.45. How about when n =
80,p = 0.1? Take another snapshot. What changes do you observe in the distribution as the parameters change? Watch both the change in shape as well as the changing number on the x and y axes.
