Data Set 14 in Appendix B lists measured reading levels for 12 pages randomly
selected from J. K. Rowling’s Harry Potter and the Sorcerer’s Stone. The Flesch-
Kincaid Grade Level measurements are summarized with these statistics: n=12, x= 5.075, s=1.168. Use a 0.05 significance level to test the claim that the reading level for a typical page can be shown to be above grade 4.
