Katie has 5 marbles in her book bag 3 Yellow (Y1, Y2, Y3) and 2 black marbles (B1 and B2). She is doing an experiment for her class where she picks one marble at a time randomly from her book bag. Katie stops picking marbles when she selects a black marble.

1. show the possible outcomes in a tree diagram

2. what are the possible values of the discrete random variable (x) that represent the total number of yellow marbles that can be picked before a black marble can be picked. Make probability distribution for each value and all components that are needed for each value.

A jar contains 2 green marbles, G1 and G2, and 4 yellow marbles, Y1, Y2, Y3, and Y4. Imagine that we do not know this. Suppose that our parameter p of interest is the proportion of marbles in the jar that are green. We will be allowed to take three marbles out the jar (all at once, without replacement). We will estimate p by looking at ˆp, the proportion of marbles in our sample that are green. (a) Write down...

Tommy has a bag with 7 marbles in it, and decides to draw 3 marbles from the bag randomly. The marbles in the bag are all the same, but some of the marbles in the bag are red and some are purple. If we decide to test the null hypothesis "More red marbles than purple marbles" and the alternative hypothesis "More purple marbles than red marbles", what would be the level of significance? We will make the Rejection Region the...
