Researchers wanted to determine if there was an association between daily cantaloupe consumption and the occurrence oi skin cancer. The researchers looked at 94.799 women and asked them to report their cantaloupeeating habits. The researchers also determined which oi the women had nonmelanoma skin cancer. After their analysis, the researchers concluded that consumption oi two or more servings oi cantaloupe per day was associated with a reduction in nonmelanoma skin cancer. Complete parts (a) through (c) below, (a) What type of observational study was this? Explain. O A. This was a cohort study because it identied a group of individuals to participate in the study and observed the group over a long period oi time. O B. This was a case-control study because individuals that had a certain characteristic were matched with those that did not. 0 C. This was a cross-sectional study because all information about the individuals was collected ata specic point in time. (b) What is the response variable in the study? Is the response variable qualitative or quantitative? What is the explanatory variable? What is the response variable in the study/.7 Is the response variable qualitative or quantitative? O A. The response variable is the number of individuals who participate in the study who eat two or more servings of cantaloupe per day. The response variable is quantitative. O B. The response variable is whether the woman has nonmelanoma skin cancer or not. The response variable is qualitative. O C. The response variable is consumption of cantaloupe. The response variable is quantitative. O D. The response variable is the number of individuals who participate in the study. The response variable is quantitative. What is the explanatory variable? 0 A. The explanatory variable is consumption oi cantaloupe. O B. The explanatory variable is the number of individuals who participate in the study. O C. The explanatory variable is the number of individuals who participate in the study who eat two or more servings of cantaloupe per day. 0 D. The explanatory variable is whether the woman has nonmelanoma skin cancer or not. (c) In their report, the researchers stated that "Alter adjusting for venous demographic and lifestyle variables, daily consumption oi two or more servings was associated with a 30% reduced prevalence oi nonmelanoma skin cancer." Why was it important to adjust ior these variabla'? O A. The researchers may be concerned with confounding that occurs when the eitects of two or more explanatory variables are not separated or when there are some explanatory variables that were not considered in a study. but that affect the value oi the response variable. 0 B. The researchers were sure that various demographic and Iiiestyie variables had greater inuence than daily consumption oftwo or more servings. 0 C. The researchers wanted to ensure that the sample was large enough in order to periorrn inference. O D. The researchers wanted to ensure that the study was representative at the entire population, so they were likely to adjust the responses to match actual data collected for the entire population.
