Question: a) The critical value of t for a 90 % confidence interval with df=7. b) The critical value of t for a 98 % confidence interval with df=108. a) The critical value of t for a 90 % confidence interval with df=7. Since 95% is the most common confidence level, we will find the critical value for constructing a 95% confidence interval. For a 95% confidence interval, α = 1 − 0.95 = 0.05, thus α 2 = 0.025. Using the 'Normal Critical Values' applet above, we find that when α 2 = 0.025, zα 2 = 1.96. A confidence interval is calculated using the following general formula: Confidence Interval = (point estimate) +/- (critical value)* (standard error) For example, the formula to calculate a confidence interval for a population mean is as follows: Confidence Interval = x +/- z* (s/√n) where: x: sample mean. z: the z critical value.Steps for Calculating a Confidence Interval. 1.
