These values can be calculated evaluating the quantile function (also known as "inverse CDF" or "ICDF") of the chi-squared distribution; [24] e. g., the χ 2 ICDF for p = 0.05 and df = 7 yields 2.1673 ≈ 2.17 as in the table above, noticing that 1 – p is the p-value from the table.
For example, when testing the null hypothesis that a distribution is normal with a mean less than or equal to zero against the alternative that the mean is greater than zero (:, variance known), the null hypothesis does not specify the exact probability distribution of the appropriate test statistic.
Developed countries have generally more advanced post-industrial economies, meaning the service sector provides more wealth than the industrial sector. They are contrasted with developing countries , which are in the process of industrialisation or are pre-industrial and almost entirely agrarian , some of which might fall into the category of ...

In 2004, for example, there were 4,012 more deaths than births, although for the subsequent five years this process had been reversed with 4,342 more births than deaths in 2008. The long-term reversal in the declining birth rate of the 1990s was confirmed in 2009 when the Registrar General for Scotland reported that with 60,000 births recorded ...
Λ is the capacity to clear the neighbourhood (greater than 1 for planets) by Stern & Levison (2002): [28] Λ = k m 2 a − + 3 / 2 , where k = 0.0043 for m in units of yottagrams (10 18 metric tons) and a in astronomical units (AU), where a is the body's semi-major axis.
That legislation had reduced the rate from 6.2% to 4.2% for the 2011 calendar year only. The initial 2012 extension was for two months, rather than the full-year extension which had been sought; the legislation also extended unemployment benefits as well as a measure preventing a drop in rates for Medicare reimbursement ; the spending for these ...
