Answer:- Option (A) " Presence / absence of a given amount of caffeine " is the correct answer.
Independent variable is the cause of a change while, on the other hand, the dependent variables are the effects of that change.. In this question, amount of caffeine is the cause of affecting our appetite (change). Thus, the presence/ absence of a given amount of caffeine is the independent variable.

You want to know whether national disasters significantly affect anxiety. You use an established anxiety scale with μ = 50, σ = 45). You sample N = 87 individuals from San Francisco right after a major earthquake, and the sample has M = 70. Identify the independent (+levels) and dependent variables. Does the independent variable significantly affect the dependent variable? What do you conclude? Use ɑ = 0.05.

FOR THE FOLLOWING SITUATIONS, INDICATE WHICH STATISTICAL TEST WOULD BE MOST APPROPRIATE. EXPLAIN YOUR RATIONALE. Your rationale should include the following information: 1) What is the research question.. Are we looking for differences between or among groups.. Are we trying to quantify the relationship between/among variables?... Are we asking questions about categorical or nominal variables? 2) What is the level of measurement of the key variables in question? A. A researcher wants to know whether or not the number of...

A researcher is interested in determining whether or not review sessions affect exam performance. The independent variable, a review session, is administered to a sample of students (n=9) in an attempt to determine if this has an effect on the dependent variable, exam performance. Based on information gathered in previous semesters, I know that the population mean for a given exam is 24. The sample mean is 25, with a sample standard deviation (s) of 4. 1. State the Hypothesis...

Most of what we know about the lac operon in E. coli has come from the genetic analysis of various mutants. Below is a list of mutants for regions of the operon. A + superscript indicates no mutation and normal function of that region, - indicates a knock out and no function of that region, c indicates the mutation resulted in constitutive action of that region. The effect of the mutation is determined by expression of the lacZ gene as...
