Concept explainers
The director of library services at Fairmont College did
a survey of types of books (by subject) in the
circulation library. Then she used library records to
take a random sample of 4217 books checked out last
term and classified the books in the sample by
subject. The results are shown below.
Subject % of Books in circ library #of books in the sample
on this subject on this subject
Business 32% 1210
Humanities 25% 956
Natural 20% 940
Science
Social Science 15% 814
Other subjects 8% 297
Using a 5% level of significance, test the claim that the
subject distribution of books in the library fits the
distribution of books checked out by students.
Please show me how to do this on a Ti84 calculator.
Thank you
