Question

For a confidence level of 99% with a sample size of 19, find the critical t value.

Answer 1

Upon using a t -table or a calculator, we see that the critical t -value for this 99% confidence interval is t0.005=2.581.
I hope this is right

Answer 2

To find the critical t value for a confidence level of 99% with a sample size of 19, we can use a t-distribution table or a calculator.

Using a t-distribution table with 18 degrees of freedom (19 - 1 = 18), we can find the critical t value for a two-tailed test at a 99% confidence level to be approximately 2.878.

Therefore, the critical t value for a confidence level of 99% with a sample size of 19 is 2.878 (rounded to three decimal places).
