Suppose N = 10 and r = 4. Compute the hypergeometric probabilities for the following values of n and x. If the calculations are not possible, please select “not possible” from below drop-downs, and enter 0 in fields. Round your answers, if necessary. n = 4, x = 2 (to 2 decimals).

A schematic spectrum of the planet Mars is shown below. Keeping in mind that Mars reflects visible sunlight and emits infrared light, refer to the numbered features of the graph and answer the following questions. For each answer, fully explain your reasoning. In your two reply posts this week, find a student that disagrees with you on one of the questions and either try to convince them of your reasoning (if you still believe you are correct), or tell them what part of their reasoning convinced you that they are correct. (The correct answers will be posted after the assignment is due!) 1) Which of […]

A Bureau of National Affairs survey found that 79% of employers provide their workers a two-day paid Thanksgiving holiday with workers off both Thursday and Friday (USA Today, November 12, 2009). Nineteen percent of employers provide a one-day paid holiday with workers off Thanksgiving Day. Two percent of employers do not provide a paid Thanksgiving holiday. Consider a sample of 120 employers.Round your answers to four decimal places. a. What is the probability that at least 85 of the employers provide a two-day paid Thanksgiving holiday? b. What is the probability that between 90 and 100 employers provide a two-day […]
