Determine the critical value(s) for a right-tailed test of a population mean, statistics homework help
I attached the t-distribution area in right tail document.
(a) Determine the critical value(s) for a right-tailed test of a population mean at the α = 0.10 level of significance with 20 degrees of freedom.
(For the answer, please make sure you put ±, -, or + before the answer. Thank you.)
(Round to 3 decimal places as needed)
(b) Determine the critical value(s) for a left-tailed test of a population mean at the α = 0.10 level of significance based on a sample size of n =15.
(For the answer, please make sure you put ±, -, or + before the answer. Thank you.)
(Round to 3 decimal places as needed)
(c) Determine the critical value(s) for a two-tailed test of a population mean at the α = 0.05 level of significance based on a sample size of n =17.
(For the answer, please make sure you put ±, -, or + before the answer. Thank you.)
(Round to 3 decimal places as needed)
Please make the answers straight forward… thanks.
