Interval definition statistics example
WebThe critical value can be determined as follows: Step 1: Subtract the confidence level from 100%. 100% - 95% = 5%. Step 2: Convert this value to decimals to get α α. Thus, α α = 5%. Step 3: If it is a one-tailed test then the alpha level will be the same value in step 2.
