This paper evaluates 29 methods for obtaining a two-sided confidence interval for a binomial proportion (16 of which are new proposals) and comes to the conclusion that: Wilson's classic method is only optimal for a confidence of 99%, although generally it can be applied when n50; for a ...
determined with a TCID50assay on MDCK cells. Titres are shown in TCID50 ml−1. Each group contains 10 mice. An unpaired two-tailedt-test of 46B8 versus Tamiflu and the combined treatment versus 46B8 or Tamiflu alone at day 4 and 6 giveP<0.05. Dotted line: detection limit of the ...
P-values were computed using two-tailed ‘N-1’ Chi-squared test with 95% confidence interval. Asterisks represent P-values < 0.0001. b) RNA-expression of genes connected to different classes of 2i-specific enhancers. cHiC was used to assign enhancer–promoter connections. Box=5-75th ...

Correlogram showing the spatial autocorrelation coefficient (r) within four local populations ofZingiber zerumbetwithin the microgeographic area. (U and L represent the 95% two-tailed confidence interval, which was calculated based on 999 permutations; a-d–local populations DS1, DS2, MLH and HJC)...
Find the critical value of x^{2l} and x^{2r} corresponding to a sample size of 19 and a confidence level of 99% if the test is two-tailed. Find the value of -z_{alpha / 2} that corresponds to a level of confidence of 94.76 per...
Results of Bayesian t tests (two-tailed with a Cauchy prior = 0.707) of the mean amplitude difference of aware-correct trials minus unaware- correct trials. The BF10 expresses the likelihood of the data given the alternative hypothesis relative to the likelihood of the data given the null ...
