3. Determine the critical value for a 95% level of confidence (p A: To calculate the critical value in R, you can use the following syntax: To find Z critical value… Q: (1) The value of 'C' (ii) Marginal distribution functions of X and Y. A:
For example, if the confidence level is 85%, here is the equation to determine the alpha value: a = 1 - (85/100) = 0.15. 2. Calculate critical probability. The next step is finding the critical probability, or critical value, using the alpha value that was calculated in the first equation. In this equation, "p * " represents the critical
The Z critical value is consistent for a given significance level regardless of sample size and numerator degrees. Common confidence levels for academic use are .05 (95% confidence), .025 (97.5%), and .01 (99%).

Z - score is a statistical measurement that describes a value's relationship to the mean of a group of values. Mathematically - where - {Z} = standard score {x} = observed value {μ} = mean of the sample {σ} = standard deviation of the sample. Given is that the critical value for {z*} for a hypothesis test of the claim at 5% significance is {z
