In constructing a confidence interval for the population mean using the t-distribution, we often need the degrees of freedom (df), confidence level, and the critical value. Use the Student t-distribution to determine the missing values in the table below. Report the positive t critical value accurate to 3 decimal places. Sample Degrees of size Confidence Critical freedom level value (t) 16 1.337 26 2.060 20 99% 2.575 X 29 90% 2.575 X
