2. Complete parts (a) through (c) below. (a) Determine the critical value(s) for a right-tailed test of a population mean at the a= 0,01 level of significance with 10degrees of

freedom.(b) Determine the critical value(s) for a left-tailed test of a population mean at the a = 0.05 level of significance based on asample size of n= 15.(c) Determine the critical value(s) for a two-tailed test of a population mean at the a = 0,05 level of significance based on asample size of n = 17. (a) terit = (1).(Round to three decimal places as needed.) (b) terit =(2)(Round to three decimal places as needed.) (c) erit = (3).%3D(Round to three decimal places as needed.)
