The stability that Windows 10 offers would have been enough for most after the uncertainty that accompanied Windows 8 and 8.1, but Microsoft surprised its user-base with updates that brought significant additions and improvements. It’s not that the OS hasn’t had its problems, but that the team behind has been quick to snuff them out.
MedCalc manual: Test for one proportion.(Version 22.009 accessed July 6, 2023) See also Kirkwood BR, Sterne JAC (2003) Essential medical statistics, 2 nd ed.Fleiss JL, Levin B, Paik MC (2003) Statistical methods for rates and proportions, 3 rd ed.Clopper C, Pearson ES (1934) The use of confidence or fiducial limits illustrated in the case of the binomial.Altman DG (1991) Practical statistics for medical research.MedCalc calculates the "exact" Clopper-Pearson confidence interval for the observed proportion (Clopper & Pearson, 1934 Fleis et al., 2003). If the P-value is less than 0.05, the hypothesis that the observed proportion is equal to the pre-specified proportion value is rejected, and the alternative hypothesis that there is a significant difference between the two proportions can be accepted. The P-value is the area of the normal distribution that falls outside ± z (see Values of the Normal distribution table). Where p is the observed proportion p exp is the Null hypothesis (or expected) proportion and se( p) is the standard error of the expected proportion: The significance level, or P-value, is calculated using a general z-test (Altman, 1991): Null Hypothesis value (%): the pre-specified proportion (the value to compare the observed proportion to), expressed as a percentage.Sample size: the sample size or total number of observations.Observed proportion (%): the observed proportion, expressed as a percentage.This test is not performed on data in the data table, but on statistics you enter in a dialog box.
The Test for one proportion can be used to test the hypothesis that an observed proportion is equal to a pre-specified proportion.
