As instructed in your video/slides, generate a written series of 20 “heads” and “tails” as if you’ve flipped a coin 20 times (just write “H” or “T”)
Now, flip a coin 20 times—it is very important that you actually flip a coin and record what you observe!
Do you see anything different between the two series?

Flip a coin 10 times and record the observed number of heads and tails. For example, with 10 flips one might get 6 heads and 4 tails. Now, flip the coin another 20 times (so 30 times in total) and again, record the observed number of heads and tails. Finally, flip the coin another 70 times (so 100 times in total) and record your results again. We would expect that the distribution of heads and tails to be 50/50. How...

Option 1 or 2.
Option 1: Use the NOAA data set provided, to examine the variable DX32. DX32 represents the number of days in that month whose maximum temperature was less than 32 degrees F. The mean of DX32 during this time period was 3.6. Using Excel, StatCrunch, etc, draw a histogram for DX32. Does this variable have an approximately normal (i.e. bell-shaped) distribution? A normal distribution should have most of its values clustered close to its mean. What kind...

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...

East Coast Digital (ECD) produces high-quality audio and video equipment. One of the company’s most popular products is a high-definition personal video recorder (PVR) for use with digital television systems. Demand has increased rapidly for the PVR over the past three years, given the appeal to customers of being able to easily record programs while they watch live television, watch recorded programs while they record a different program, and save dozens of programs for future viewing on the unit’s large...
