1647. 10,000 New York City Road Runner members were surveyed and classified based on the number of hours per week that they ran. The runners were classified as 'Running more than 10 hours per week' and 'Running less than 10 hours per week.' Runners were then followed for the next 5 years to determine which runners develop stress fractures.
Incidence rates of stress fractures per year per 1,000 runners:
Running less than 10 hours per week: 0.28
Running more than 10 hours per week: 0.63

Calculate the relative risk of developing stress fractures associated with running more than 10 hours per week.

Describe in words how you would interpret the results.

2031. One common association that people have is called conditioned taste aversion, which occurs when you eat or drink something and then get sick. A conditioned taste aversion is most likely to occur when the food or drink is relatively unfamiliar. Suppose you have acquired a conditioned taste aversion to tequila. Identify the unconditioned stimulus, unconditioned response, conditioned stimulus, and conditioned response in this example. Next, write down an example of something you have learned recently that involves operant conditioning. Provide a clear description of the behavior that is being conditioned, describe and label the reinforcer (positive or negative) influencing the behavior, and specify the schedule of reinforcement involved in this behavior.

1st Part:
With respect to the taste aversion part of the question, it's important to clearly distinguish a) the unconditioned stimulus from the conditioned stimulus, and b) the unconditioned response from the conditioned response. Remember, the unconditioned response does not need to be the same as the conditioned response.

2149. Jamal wants to buya Sony PlayStation 2 with accessories. The entire package costs $234.10. Jamal has already saved $39. Every Saturday night Jamal's Aunt Eunice comes over for dinner. Aunt Eunice has no children and is always interested in what Jamal is doing. He told her about the PlayStation and she made him a deal. Since she believes that saving money for the things that you want is a virtue, she will match every dollar Jamal saves 3 to 1 beginning at that moment. She will not match the $39 he has already saved. When Jamal has saved all of the money he needs, Aunt Eunice will take him, after Saturday night dinner, to buy the PlayStation. Jamal figures that he can save $4 per week. The Saturday that Aunt Eunice came for dinner was April 1st. When can Jamal buy his PlayStation? Show how you figured it out. You may use models, pictures, tables, etc. but you must also write and solve an equation, labeling your variables. Give a written explanation of your work. (Answered)

epicenter located relative to the seismograph and why?
