Determine the critical values for these tests of a population standard deviation: (a) A right-tailed test with 11 degrees of freedom at the α = 0.1 level of significance. (b) A left-tailed test for a sample of size n = 26 at the α = 0.01 level of significance. (c) A two-tailed test for a sample of size n = 27 at the α = 0.1 level of significance. (a) The critical value for this right-tailed test is 17.275. (Round to three decimal places as needed) (b) The critical value for this left-tailed test is [ ].
