State whether the data described below are discrete or continuous, and explain why. The weights (in tons) of the trees in a forest <:> Choose the correct answer below. 0 A. The data are continuous because the data can only take on specic values. 0 B. The data are continuous because the data can take on any value in an interval. (9 C. The data are discrete because the data can take on any value in an interval. 0 D. The data are discrete because the data can only take on specic values. Identify the type of sampling used (random, systematic, convenience, stratified, or cluster sampling) in the situation described below. A woman is selected by a marketing company to participate in a paid focus group.

E) Choose the correct answer below. 0 A. The value is a parameter because it describes some characteristic of a population. 0 B. The value is a parameter because it describes some characteristic of a sample. (9 c. The value is a statistic because it describes some characteristic of a population. 0 D. The value is a statistic because it describes some characteristic of a sample. Determine whether the study is an experiment or an observational study, and then identify a major problem with the study. A medical researcher tested for a difference in systolic blood pressure levels between male and female students who are 12 years of age. She randomly selected four males and four females for her study. This is an observational study because the researcher does not attempt to modify the individuals. What is a major problem with the study? O A. This is a convenience sample with voluntary response, which has a high chance of leading to bias. 0 B. There is no blinding, which has a high chance of leading to bias. 0 C. The sample includes male and female students. D. The sample is too small. Identify which of these types of sampling is used: random, systematic, convenience, stratied, or cluster. A large company wants to administer a satisfaction survey to its current customers. Using their customer database, the company randomly selects 70 customers and asks them about their level of satisfaction with the company.
