... exactly one television, a 0.5% chance that it will own exactly six televisions, and a 62% chance that it will own no more than two televisions. We can now use the completed probability distribution to determine the mean (or the expected value) of the random variable. We are fortunate in this problem ...

Chapter Thirteen: Probability
... Section Three: The Fundamental Counting Principle Sometimes we need to determine how many different ways that a series of events can happen. There are two different methods for doing this. One method is by using a tree diagram. However, if there are multiple events then we can use the fundamental c ...

Nonparametric statistics and model selection
... Suppose we want to see if a particular complex statistic is significantly different between two groups. If we don’t know the distribution of the statistic, then we can’t assign any particular probabilities to particular values, and so we can’t say anything interesting after computing a statistic fro ...

... Reactions to Poison Ivy. A random sample of 1000 individuals with poison ivy allergies participated in a study to gauge their reactions to the oil from a poison ivy plant, Oil from the poison ivy plant was rubbed on the skin of the individual. Half of the subjects had the oil washed off within 5 min ...

Sampling from a population of “0”s and “1”s
... If the population is non-normal with mean µ and known standard deviation σ, using CLT: • If n ≥ 30, Ȳ is approximately normally distributed with mean µ and standard deviation √σn . • When you have no information about the shape of the population distribution, you shouldn’t assume you can use the CL ...
