Jul 21, 2023 · If the universe is "flat" and composed mostly of ordinary matter, then the age of the universe is 2/(3 H0). If the universe has a very low density of matter, then its extrapolated age …

Dec 19, 2014 · The confusion here is that you're mixing up conditional and unconditional probability. Power is a conditional probability: P(reject H0|H0 false).

Jul 6, 2023 · A p-value is the probability of the observed data (or of more extreme data points), given that the null hypothesis H0 is true, defined in symbols as p(D|H0). On the same page, …

Jan 2, 2019 · The alternative hypothesis, or rather the (infinitely large) set of alternatives is defined based on the hypothesis, i.e. for H0: μ <= 0, the set of alternatives included every u1 > …

With the rationale that H0 must include the equality, which in this case is greater or equal to 30%. Her solution than failed to reject the null hypothesis and concluded that the researcher's claim …

assuming H0 was true what is the probability of observing the data in front of us 3/ this is done via test statistic (assuming H0!), which is a random variable (randomness comes from random …

May 10, 2020 · What is H0 for the Chi-squared Test of Independence? I know, it sounds like a very easy question but check this out. According to R Tutorial (link below), from the answer of …

Feb 11, 2021 · (1) H0 is a formal model and (as far as I think at least, and I'm not alone) no formal model will ever be true in reality, so the probability that H0 is true will be zero whatever the test …

However, if in fact the rejection probability for the "equal" is equal to the supremum over the rest of the null hypothesis (as is the case for most tests although one could imagine tests for which …

So the null hypothesis is something you want to check against something else. Here you want to check if the average time that Michael works is different (either has larger or smaller value) …
