Find the critical value(s) to test the hypothesis H0: μ = 13 at the significance α = 0.01, given a sample with n = 12, x̄ = 14.2, and σ = 2.2. Options: a. -2.330 b. -2.718 c. ±3.106 d. ±3.055 e. -2.681 f. ±2.575

Use a table or technology to calculate the critical value(s) using a t-distribution in each of the following cases. (Round your answers to three decimal places.) (a) two-tailed test, df = 9, α = 0.01 ± (b) upper-tailed test, df = 12, α = 0.01 (c) lower-tailed test, n = 26, α = 0.025 (d) lower-tailed test, n = 28, α = 0.005 (e) two-tailed test, n = 43, α = 0.01 ±
Consider the following test performed with the level of significance 0.01: H0: μ = 23.5 HA: μ > 23.5 A random sample of size 47 is obtained from a normally distributed population. The population standard deviation is equal to 4.2. The sample mean happened to be 22.6. For this hypothesis test, what will be the critical value (the relevant z-alpha)? Round the answer to three decimal places.
