z–scores and Confidence Intervals
What is the z value for a 91.4% confidence interval estimation? Using a z table, write down the probabilities for the following intervals and sketch the respective areas under a normal distribution curve: P(z1.49) P(z\geq 1.49) P(0.14 z1) P(-\inftyz +\infty)...
‘ylab’, ‘main’, ‘cex.axis’, ‘cex.lab’. Furthermore, an annotation with the main test statistics can be added to the plot by specifying ‘annotation = TRUE’ and the pointwise confidence intervals of the plot by specifying “CI = TRUE”. For more options regarding the annotation ...
Obtaining Confidence Intervals for a Population Mean When σ Is Known The z-interval procedure works reasonably well even when the variable is not normally distributed and the sample size is small or moderate, provided the variable is not too far from being normally distributed. Thus we say that...
This study applied the social exchange and social identity theories to investigate the association among resonant leadership, self-efficacy, organizational
p-values for panels a-b and d were calculated using the Wilcoxon rank sum test (two-tailed), and for panel h using the Fisher’s exact test (two-tailed). L: Low; M: Medium; H: High; CI: confidence interval. Nfe2l2-KO: Foxn1Cre-Nfe2l2flox/flox; Ctrl: control, Foxn1Cre-Nfe2...

Here is a formula for calculating the z: z = (x–μ)/σ where x– individual value μ– mean σ– standard deviation. Interpretation of the formula: Subtract the mean of the values from the individual value Divide the difference by the standard deviation. ...
Four of the LDL-C values could not be calculated because of triglyceride concentrations greater than 400 mg/dL (4.52 mmol/L) and were treated as missing data. At all time points, the statistically significant findings for HDL-C and triglycerides concentrations favored the Atkins group (Table 3...
