6. Step 1: A developer of a virtual-reality (VR) teaching tool for the deaf wants to compare the effectiveness of different navigation methods. A total of 40 children were available for the experiment, of which equal numbers were randomly assigned to use a joystick, wand, dancemat, or gesture-based pinch gloves. The time (in seconds) to complete a designed VR path is recorded for each child. State whether the following statement is True or False: The response variable is the time to complete a VR path and the populations are children using different navigation methods. True False Step 2: For each of the following situations, identify the response variable and the populations to be compared, and give , , and . Give , , and . Fill in the blanks: (Give your answers as whole numbers.) 1) _______ . 2) _______ . 3) _______ . 4) _______ . 5) _______ . 6) _______ . Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Answer 6 Step 3: To study the effects of pesticides on birds, an experimenter randomly (and equally) allocated 65 chicks to five diets (a control and four with a different pesticide included). After a month, the calcium content (milligrams) in a 1-centimeter length of bone from each chick was measured. State whether the following statement is True or False: The response variable is the effect of pesticides on birds and the populations are the five diets.
