**Question:**For a confidence level of 99% with a sample size of 19, find the critical t value.**Explanation:**To find the critical t value for a given confidence level and sample size, you need to refer to the t-distribution table or use statistical software. The degrees of freedom (df) in this case would be the sample size minus one, which is 18 (19 - 1 = 18).A confidence level of 99% corresponds to an alpha level of 0.01. The critical t value is the value that separates the most extreme 1% of the data from the rest. For greater accuracy, a two-tailed t-distribution should be used, since a confidence interval is typically two-tailed. Using a t-distribution table or statistical software with df = 18 and alpha = 0.01 (two-tailed), you would find the critical t value.
