1) a) A drawer contains 9 white socks and 7 black socks. Two different socks are selected from the drawer at random. What is the probability that both of the selected socks are white? b) A box contains 10 white marbles and 7 black marbles. Suppose we randomly draw a marble from the box, replace it, and then randomly draw another marble from the box. (This means that we might observe the same marble twice). What is the probability that...

Suppose that a drawer contains 8 marbles: 2 are red, 2 are blue, 2 are green, and 2 are yellow. The marbles are rolling around in a drawer, so that all possibilities are equally likely when they are drawn. Alice chooses 2 marbles without replacement, and then Bob also chooses 2 marbles without replacement. Let Y denote the number of red marbles that Alice gets, and let X denote the number of red marbles that Bob gets. a. Find probability...

I have four socks in a drawer; each is either black or white. Suppose that my null hypothesis is H0 : There are exactly two black socks. We decide on the following test: we take out two socks at random (all at once and without replacement). We reject H0 if the two socks are the same color. [Note: this test doesn’t make a whole lot of sense; this is just to practice the ideas.] a) What is the significance level...
