Determine whether the following scenarios are examples of an observational study, a sample survey, a census or an experiment. You decide to give a questionnaire about cell phone use at SHS to 10 math classes. 0 Observational Study 0 Sample Survey 0 Census 0 Experiment A group of 2000 people signed up for a study that measured the effects of a new weight loss medication. The study noted that the medication might work differently in men than in women. The study.r planned to use an established weight loss medication. the new medication, and a fake treatment that contained no medication. What other lurking variables should the researchers take into account when designing this experiment? 0 Diet and exercise 0 Diet 0 Diet and genetics 0 Diet. exercise, genetics A group of 2000 people signed up for a study that measured the effects of a new weight loss medication. The study noted that the medication might work differently in men than in women. The study planned to use an established weight loss medication, the new medication, and a fake treatment that contained no medication. Identify the response and explanatory variables in this experiment. 0 Explanatory: weight loss medication; Response: how much weight is lost 0 Explanatory: how much weight is lost; Response: weight loss medication 0 Explanatory: Gender: Response: how much weight is lost 0 Explanatory: how much weight is lost; response: gender The administration wants to survey 4 math teachers about what they did in their classes to prepare for the ACT Aspire test. Here are the math teachers' names: Bloodworth, Brown, Chandler, Fitzgerald, Fox, Lamb, Lynn, Mahler, Martin, Mcdougald, Richardson, Ross, Salmon, Seals, Smith, Warner, Wertenberger. Use the Random Digits Table, starting at line 104, to select four math teachers.

The study noted that the medication might work differently in men than in women. The study planned to use an established weight loss medication. the new medication, and a fake treatment that contained no medication. What type of experiment design should they make? 0 Randomized comparative because the medication would work the same in both men and women. 0 Block, broken into men and women because the medication might work differently
