11.

(a) Look up and write down the F cutoff at the .01 level for distributions with 1 degree of freedom in the numerator and 10, 20, 30, and 60 degrees of freedom in the denominator.

(b) Take the square root of each and write it down next to it.

(c) Look up the cutoffs on the t distribution at the .01 level (twotailed)

using 10, 20, 30, and 60 degrees of freedom, and write it down next to the corresponding F square root. (The results should be identical, within rounding error.)
