Question

LeBron James of the Miami Heat hit 765 of his 1354 field goal attempts in the 2012/2013 season for a shooting percentage of 56.5%. Over the lifetime of LeBrons career, can we say he is more likely than not to make a field goal? Describe the parameter of interest. the proportion of all shots made by NBA players in LeBrons career LeBrons long-run proportion of making a field goal the number of shots LeBron made in the 2012/2013 season the proportion of shots LeBron made in the 2012/2013 season what statistical term is given to the value 56.5%? statistic parameter sample chance modelWhat value would the chance model assign to LeBrons long-run proportion of making a field goal? O 25% O 50% O 56.5% 765 Describe how to use coin flipping to simulate the 2012/2013 season under the assumption of the chance model. Flip a coin 1354 times and record the number of heads. This number represents the long-run proportion. Flip a coin 765 times and record the number of heads. Multiply this value by 1354. Flip a coin 1000 times and record the number of heads. Repeat this process 765 times. Flip a coin 1354 times and record the number of heads. Repeat this 1000 times, keeping track of the number of heads in each set of 1354Suppose coin flipping was used to simulate the 2012/2013 season under the assumption of the chance model. What would be a typical number of heads recorded from a repetition of 1354 coin flips? 56.5% of 1354 (765) will be one of the most likely values since we assume the chance model is true and the chance probability is 56.5%. Approximately ½ of 1354 (677) will be one of the most likely values since we assume the chance model is true. LeBron James is a great player so we can assume he will make at least 60% of his shots. Nothing can be known about the typical number of heads without doing the simulation.

    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...

How is the caregiver’s role different in each model? How is the patient’s role different? Answer: Physical-centered communication involves the specialists taking control of the conversation. They decide on the topics of discussion and when to end the process. The patient responds to the issues raised by the caregiver and acts accordingly. On the other hand, Collaborative communication involves a...
