A condensed study report provides data that shows that the number of wolves is correlated to the number of bats. It reports that as the wolf population increases, the bat population decreases. The study's conclusion is that increased wolf population causes decreased bat population. Which of the following choices describe the information provided. O A. There is a lack of information. The correlation needs to be identified as negative in order to confirm the causal effect. O B. There is a lack of information. More information is needed to determine if one population is causing an effect on the other. O C. All the relevant information to determine cause and effect is provided. O D. All the relevant information is provided, but it shows it is the bat population that causes the effect on the wolf population. A survey is conducted to determine how many of each of 4 types of fish anglers catch a local lake during the fishing season. The survey methodology involves distributing the survey to the local angler and cottager associations and asking them to distribute it to their members who fish on the lake. 503 people fill out the survey. The survey askes the anglers to indicate the number of fish caught for each of 4 choices. It also provides a choice for Other, with a request to indicate the species. The results indicate the most frequently caught fish by the anglers on the lake is smallmouth bass. Which statement best describes the design of this study? O A. The survey is poorly designed because it does not ask every angler who visits the lake. O B. The survey is poorly designed because it does not properly target the people who fish the lake. O C. The survey is poorly designed because it does not ask the right questions. O D. The survey is well designed because it does a good job of collecting information from people who fish the lake
