Use the tables in the back of the book to compute the following probabilities and answer the questions. clearly explain how and where you are finding your answers. (a) (i) if y is distributed t60, find p(-1.67≤y≤1.67). (ii) if y is distributed n(0,1), find p(-1.67≤y≤1.67). your answer should be written to four decimal places. (iii) compare your answers to (i) and (ii). why are these answers different? (b) if y is distributed f4,3, what are the critical values for 10%, 5%, and 1% significance levels? (c) if y is distributed χ26, find p(y< 10.64).
