a Use Table 7, Appendix 3, to find F.01 for F-distributed random variables, all with 4

Chapter 7, Problem 7.31

(choose chapter or problem)

a Use Table 7, Appendix 3, to find F.01 for F-distributed random variables, all with 4 numerator degrees of freedom, but with denominator degrees of freedom of 10, 15, 30, 60, 120, and . b Refer to part (a). What do you observe about the values of F.01 as the number of denominator degrees of freedom increases? c What is 2 .01 for a 2-distributed random variable with 4 df? d Divide the value of 2 .01 (4 df) from part (c) by the value of F.01 (numerator df = 4; denominator df = ). Explain why the value that you obtained is a reasonable value for the ratio. [Hint: Consider the definition of an F-distributed random variable given in Definition 7.3.]
