The p-value (denoted p) for a set of data is the probability that the given data (or something even more unusual) would occur if the hypothesis being tested is not true. How do you find p-value from z-statistic? To calculate the p-value, first find the test statistic, a value that...
For questions 1 to 3, find the critical region for the test statistic X,given that X has a Po(4) distribution.A single observation x istaken from a Poisson distribution X~ Po(2) and a value of 7 isobtained. Use this observation to test H: λ = 5 against H1: λ≠ 5 using a 5%...
clustered around themean. What the rule of thumb tells you in most cases is that the bulk of the data can be found pretty close to the mean (within a couple of standard deviations); The result is that those erroneous “outliers” should have very little effect on your final statistic. ...

The geometric mean is an average that multiplies all values and finds a root of the number. For a dataset with n numbers, you find the nth root of their product. You can use this descriptive statistic to summarize your data.The geometric mean is an alternative to the arithmetic mean, ...
