The numbers of words in the first complete sentence on each of 10 pages selected at random is counted in each of the books by Conover (1980) and Bradley (1968). The results were: Conover 21 20 17 25 29 21 32 18 32 31 Bradley 45 14 13 31 35 20 58 41 64 25 Perform tests to determine whether there is evidence that in these books (a) sentence lengths show a difference in centrality; (b) the variances of sentence lengths differ between authors; (c) the distributions of sentence lengths differ in an unspecified way
