Testlet 7: Three state dental public health hygienists are identifying oral health needs of persons residing in state-subsidized drug and alcohol rehabilitiation centers. Based off the study results a public health program will be created and implemented into these centers. One study compared oral lesions in persons who smoke cigarettes to those who do not smoke. This study was performed in three state rehabilitiation centers, and patient selection was done in alphabetical order and selecting every third individual from the patient list. The two dental hygienists who worked jointly for one day at each of the three sites calibrated the dental indices to be used. The dental hygienists established the hypothesis as “There is no significant correlation between cigarette smoking and oral lesions”. This is an example of what type of hypothesis?
