Order Description Evidence implicates infection with human papilloma virus as a risk factor for cervical cancer. There are over forty (40) strains of HPV. Some evidence indicates that there may be a relationship between the strain of human papillomavirus (HPV) infection and the risk of cervical cell abnormalities. A few of thstrains are deemed high-risk, while others are deemed low risk. For our purposes here, we will consider any HPV virus as belonging to either a low- or high-risk strain. Address each of the following six (6) items. Each item is worth twenty five (25) points. 1. State a null hypothesis and an alternative hypothesis. 2. Determine the level of the variables: 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 tvariable? b. If cervical cell abnormalities are measured as biopathology results of negative, CIN I, CIN II, CIN III, or Cancer in Situ (thare progressively worse levels of abnormality), what level of measurement is the variable? 3.

Step 7: 4. Compare the following population results from past studies with the sampled results from the current study to determine whether the sample is representative. Show your work and explain your rationale. In the population, 30% of cervical biopsies are negative, 40% are CIN I, 20% are CIN II, 5% are CIN III, and 5% are Cancer in Situ (CIS). A random selection of hospitals is made and a random selection of bioresults is reviewed. In the random sample of 120 biopsies, 16 are negative, 42 are CIN I, 30 are CIN II, 22 are CIN III, and 10 are CIS. In the same sample, 1 person is HPV negative, 87 are HPV positive with the low-risk strain, and 32 are HPV positive with the high-risk strain. 5. Answer the following questions based on below scenario. Suppose the statistical test you employ states that the association between the type of HPV infection and cervical cell abnormalities has a p-value of 0.06. If the alpha for the study is set at 0.05, a. What should the researcher conclude regarding the null hypothesis? Why? b. If instead of an alpha of 0.05 the researchers decided to set tpilot studys alpha at 0.10, what would the researcher conclude about the null hypothesis (p = 0.06)? 6. Address the following issues: a. If the researcher rejects the null hypothesis but does so in error, what type of error could he or she be making? What does ttype of error mean? b. If the researcher does find a statistically significant difference, does tmean it is a clinically significant difference?
