Complete question:
Dr. Lyte wishes to study speed of Reaction Time to press a button in response to the onset of a lamp. The independent variable (V) is the color of the light produced by the lamp (red, orange, yellow, green, or blue) Since only 10 participants are available, she elects to administer the IV within-subjects with all 10 participants being exposed to all five levels of the color variable. The order of the color of the light presentation is to be counterbalanced. Using concepts from the textbook, why would Dr. Lyte need to use counterbalancing in this scenario?
Answer:
Here,
Independent variable (IV) is: the color of the light produced by the lamp (red, orange, yellow, green, or blue)
We are also told only 10 participants are available.
All 10 participants are being exposed to all five levels of the color variable in the same order.
Counterbalancing is said to be a technique used when establishing task order. It helps prevent introduction if cofounding variables.
Dr. Lyte will need to use counterbalancing technique in this scenario because some of the participants may be unable to understand difference in similar colours. Example some participants may not be able to differentiate between orange and red when the red colour comes after orange.
But using counterbalancing technique, Dr. Lyte can avoid such an error.
Answer:
question one is 2,251.02
question 2 is 579.58
Step-by-step explanation:
The number of purple marbles in the bag are; 201 purple marbles
<h3>How to work out fraction of bar model?</h3>
We are told that Two-fifths of the marbles are green, and the rest are purple.
A) The image attached shows the bar model where the shaded parts denote the purple marble while the unshaded parts denote the green marbles.
B) We are told that there are 134 green marbles.
If the total number of marbles are x. Then;
(2/5)x = 134
x = 134 * 5/2
x = 335 marbles
Thus;
Purple Marbles = (3/5) * 335 = 201 purple marbles

Answer:
Step-by-step explanation:
I dont really know how to find out the variables but what i assume to do is this:
Find the square root of n and add it to m. The sum of both you divide by p. then when you figure that out, you distribute the x value into the parenthesis. This might be obvious but i looked at this question for 10 minutes and couldnt find the value sorry :(
