Find the critical value. Determine the critical values for a two-tailed test of a population mean at the α = 0.05 level of significance based on a sample size of n = 12.
Added by John C.
Step 1
Since it's a two-tailed test, we need to find the critical values for both tails. We are given α = 0.05, so we need to find the critical values that correspond to 0.025 in each tail (because 0.05/2 = 0.025). Show more…
