A shelter has 24 dogs up for adoption. Suppose you want to adopt 2 of them. How many different ways could you choose 2 dogs from the 24? We are interested in analyzing data from bike sharing in LA. Use O to denote a one-way route and A to denote an annual pass. The probability that someone has a one-way trip route is 84.74%. The probability that they have an annual pass is 2.77%. The probability that they have an...

For this assignment, suppose that a fence is recording entry and exit into the park via a string as the gate swings open and folks walk in or out with their pet. For example, C++ DP+dp+CP+cp would indicate that an adult dog and an adult entered the park, then a puppy and child entered the park, then an adult cat and an adult entered the park and finally a kitten and a child entered the park. From this information, note...

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...
