Obrain a list the students in your class in order from highest test average to lowest. From the list of students, using a stratified random sample, select every second student on the list and randomly assign half of them to drink 32oz. of Diet Coke before the math exam. The other half will drink nothing but water before the exam. Have each student take the exam and compare the scores between the students who drank Diet Coke and the students who drank water.
Sampling method: Stratified random sample
Independent variable: Consumption of Diet Coke
Dependent variable: Score on the math exam
Control: Group drinking nothing but water
Experimental: Group drinking 32 oz of Diet Coke
You would evaluate the results by comparing the mean score of the water drinkers' test to that of the Diet Coke drinkers. If the Diet Coke drinkers perform poorly, then we can generalize the results to the class.
The correct answer for the problem is c
As you can see both drawings take up the same amount of surface area and the same amount of surface area is colored. The one on the right has 12 spaces, while the one on the left only has 3.
It would be a Liberal Arts College. That is generally a four year university, instead of a two year program.
Answer:
The correct answer is letter "B": The wire brush can remove too much material from the posts of the battery.
Explanation:
While cleaning a battery there are several considerations to be taken in order not to damage its function. At the moment of cleaning the posts, we must be very careful since this is the principal contact with the vehicle cables. In front of any damage, the vehicle may not even start.
Thus, using a soft wire brush with an electric drill is not appropriate since it could remove more material than the necessary from the posts.
