The quantitative determination of the 5f population inα-Pu andδ-Pu is reconsidered in detail. Trends across the 5f series are discussed, including atomic sizes, 5f populations and computational modeling. A recently developed and novel approach, based upon a thermodynamical evaluation of entropies, is presented. Finally, a detailed spectroscopic analysis of the original Pu N4,5and O4,5x-ray absorption spectroscopy has been performed, including the correction of a fundamental flaw in the Electron Energy Loss Spectroscopy (EELS) measurements. Thus, the determination of the 5 f occupation (n) in elemental Pu has been re-evaluated with the result thatn= 5.0 ± 0.1 forαPu andn= 4.9 ± 0.2 forδPu. These values are significantly lower than the value of ∼5½ that was propagated earlier.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
