Mathematical Statistics

(Statistical Inference) - 2nd edition, Casella and Berger

* Consider the following experiment:

You simultaneously toss 6 coins.

You count the number of "heads" and record whether it is an odd or even number.

Then you toss the 6 coins again.

The process continues until the second time that you get an even number of "heads".

Let X be the number of tosses required to complete the process.

Find the distribution of X and give its mean and variance.

(Since the range of X is countable, then X is a discrete random variable.)

    Use R - stuido 6. Consider a fair coin. If Y = # of tosses until first H, what are P(success), EY, and VY? 7. Next, take a quarter and record # of tosses until first H. Do this experiment 30 times: so that your first experiment consists of your tosses up to your first H, and you record the number of T before the coin came up heads. Then you pretend to start over: reset your count and toss...

    Can Dogs Understand Human Cues? EXPLORATION Dogs have been domesticated for about 14,000 years. In that time, have they been able to develop an understanding of human gestures such as pointing or glancing? How about simi lar nonhuman cues? Researchers Udell, Giglio, and Wynne tested a small number of dogs in order to answer these questions. In this exploration, we wll first see whether dogs can understand human gestures as well as nonhuman gestures. To test this, the researchers positioned...
