For the following scenario Answer the following questions. Assume the data is from simple random samples and is normally distributed unless otherwise stated. 1. What are the variable(s) in the study? (include units) 2. What type of variable(s) are they? (Level of measurement) 3. What statistical test is most appropriate to use in analyzing the data given the information provided. A developmental psychologist is investigating the impact of sugar consumption on children's activity level. She measures how many grams of sugar each child in a group of 40 consumes during an 8-hour period, then measures how many calories each child expends on a playground during a subsequent 30-minute play period. She wants to see if there is an association.

A researcher has 4 different concentrations of the same drug and wants to know if the concentration of the drug affects the subject's weight. They include 50 subjects in each group and measures their weight (in kg) before they are given the drug and 6 months after being on the drug and computes the change in weight for each subject. Assume the groups have constant variance.

A researcher wants to see if an intervention affects the ability of a subject to pass a test, recorded as pass/fail. You give 50 subjects the test and record who passes afterwards you give them the intervention then test them again.

You want to know if your sample of 50 subjects have an average weight of 150 pounds with a standard deviation of 9 pounds.
