Beta, β, is the conditional probability that one will not reject the null hypothesis given that the null hypothesis is really false (that is, make a Type II error). Since rejecting the null and not rejecting the null are mutually exclusive and exhaustive eve ...

... Note: The expectation of X is also called the expected value of X or the mean of X and is often denoted by µ. Example 3.2. Suppose that a fair coin is about to be flipped. If it lands on heads, you win 30 dollars. If it lands on tails, you lose 20 dollars. We can define X to be the random variable t ...

... Method A: simple random Method B: systematic Method C: Stratified Method A is the most accurate because every member of the population is equally likely to be in the sample. In Method C, the sample contains an equal number from each group, but the total numbers in each group differ significantly. So ...

... a) What are the possible values that X takes on and what are the probabilities of X taking a particular value? From the above we see that the possible values of X are the 4 values X= 0, 1, 2, 3. Said differently the sample space is a disjoint union of the 4 events { X = j } for short ( j =0,1,2,3 )w ...

... Remark 127. In the previous section we defined independence of events and now we have defined independence of random variables. How are they related? We leave it to you to check that events A1 , . . . , An are independent (according the definition of the previous section) if and only if the random v ...
