Since population standard deviation is unknown, Use t-distribution to find t-critical value. Find the t-critical value: Refer t-distribution table and look for the "t" value corresponding to degrees of freedom=19 & confidence level of 99% for the two-tail test OR Use excel function "=T.INV.2T(0.01,19)" to find the critical value of "t" for the two-tail test. Therefore, the t-critical value is Plug in all the values in the formula, we get Answer:
