Suppose that you were asked to construct a 95% confidence interval based on the standard normal distribution. Use software or a table of critical values from the standard normal distribution to determine the positive critical value, ?, for the confidence interval. Give your answer to two decimal places, rounding to the nearest value if necessary.
a) The critical value of t for a 90% confidence interval with df = 8. b) The critical value of t for a 95% confidence interval with df = 103.
