A hypothesis will be used to test that a population mean equals 12 against the alternative that the population mean is less than 12 with known variance o. What is the critical value for the test statistic Zo for the significance level of 0.010? Round your answer to two decimal places (e.g. 98.76). 21-a =
(a) Determine the critical value(s) for a right-tailed test of a population mean at the α=0.05 level of significance with 10 degrees of freedom. (b) Determine the critical value(s) for a left-tailed test of a population mean at the alphaαequals=0.01level of significance based on a sample size of n=20. (c) Determine the critical value(s) for a two-tailed test of a population mean at the α =0.10 level of significance based on a sample size of n=16.
