The NCHS report indicated that in 2002, 75% of children aged 2 to 17 saw a dentist in the past year. An investigator wants to assess whether

use of dental services is similar in children living in the city of Boston. A sample of 125 children aged 2 to 17 living in Boston are surveyed and

64 reported seeing a dentist over the past 12 months. Is there a significant difference in use of dental services between children living in

Boston and the national data using the chi-square goodness-of-fit test? (10 points)
