Question

Untitled papilloma virus (HPV) as a risk factor for cervical Evidence implicates infection with human cancer. There relationship between the strain of HPV infection and the risk of cervical cell abnormalities.A few of these strains are deemed "high-risk", while others are deemed "low risk". For our purposes here, we will 1. State a null hypothesis and an alternative hypothesis 2. Determine the level of the variables: are over forty (40) strains of HPV. Some evidence indicates that there may be a consider any HPV virus as belonging to either a low- or high-risk strain a. If HPV infection is measured as not infected, infected with a low-risk strain, or infected with a high-risk strain, what level of measurement is this variable? b. If cervical cell abnormalities are measured as biopsy pathology results of negative, CIN I, CIN IL CIN I, or Cancer in Situ these are progressively worse levels of abnormality), what level of measurement is the variable?

Answer 1

(1) Null -> there exists a relationship/association between the strain of HPV infection and the risk of cervical cell abnormalities.
Alternative -> there does not exist a relationship/association between the strain of HPV infection and the risk of cervical cell abnormalities.

(2) (a) ordinal level of measurement.
(b) ordinal level of measurement.
