The Syrian hamster has an average life span of two to three years. Although uncommon, these hamsters can sometimes live up to five years. A hamster's life span can be extended to a degree by providing it with a clean environment and fresh food daily. Continue Reading.
and substituting the estimate for gives. which is an unbiased estimator of the variance of the mean in terms of the observed sample variance and known quantities. Note that, if the autocorrelations are identically zero, this expression reduces to the well-known result for the variance of the mean for independent data.
Key thing we have to remember is we need to compute whether these are independent events or dependent events. If there are independents events, probability of A and B is the simple multiplication of there individual probabilities.eâll use an example, actually a couple of examples. We need to determine whether the events are independent or dependent and then compute their probabilities. Part A says Andrew draws a four from ten cards which are numbered 1-10.
