I am writing this question in behalf of several teachers from the Northern Utah Stats Teachers group (NUSTAT). We are curious as to the decimal accuracy that will be required on the AP Exam. Is it based on significant figures or on decimal places. Many of us are also teaching the AP Calculus program where the rule has been to round to 3 decimal places regardless of the size of the numbers involved. If Dick Scheafer or a member of the test development committee is watching, we would appreciate some guidance on this issue.
Thanks, Larry Peterson Bonneville High School 251 E Laker Way Ogden, Utah 84405
