1) Find the critical z-value(s) for a right tailed test with α = .02 . Assume a normal population. (Round to the nearest hundredth. If more than one value is found, enter the smallest critical value.) 2) Find the critical t-value(s) for a two-tailed test with n = 12, α = .05 . Assume a normal population. (Round to the nearest thousandth. If more than one value is found, enter the smallest critical value.) 3) Find χ2R for a right-tail...
