1 96 is used because the 95 confidence interval has only 2 5 on each side The probability for a z score below 1 96 is 2 5 and similarly for a z score Suppose a confidence interval of 95 has been specified for conducting a hypothesis test The critical value can be determined as follows Step 1 Subtract the confidence level from 100 100 95 5 Step 2 Convert this value
To find a critical value look up your confidence level in the bottom row of the table this tells you which column of the t table you need Intersect this column with the row for your df degrees 1 What is the 95 confidence interval rule The 95 confidence interval rule states that if we repeatedly construct 95 confidence intervals for a population parameter we
