I am working with a test statistic that is distributed as a weighted sum of chi-square distributions. Given a particular value x, how can I find its associated p-value? I believe I can use something like 1-chi2cdf(x,d) when dealing with just one ch...
P-Value: The p-value is the area of the tail beyond the calculated value of the test statistic. If the test is a left tail test, it is the area to the left of the calculated value of the test statistic. If the test is a right-t...
Answer to: Use the given information to find the P-value: The test statistic in a right-tailed test is z = 1.43. By signing up, you'll get...

Question: Calculate the test statistic , find the ranfe of p value , construct lowrt and upper confidence interval Calculate the test statistic , find the ranfe of p value , construct lowrt and upper confidence interval
The p-value is the probability that the F-distribution of all possible values of the F-statistic takes on a value greater than the actual F-statistic for a variable. If the p-value falls below a specified significance level, then the null hypothesis (that the individual elements of the var...
In an increasingly data-driven world, there seems to be a statistic for almost everything. That's especially true in college admissions as schools drill down into various data points when selecting incoming classes. For prospective students, that means an opportunity to see how they stack up to...
