Step-by-step explanation:
Answer:
(a) 3, 5 and 6
Step-by-step explanation:
In the experiment, 43 are to be given a gel that contains the tooth-whitening chemicals while the remaining 42 are to be given a placebo. Therefore, a placebo is used.
The 43 that will receive the gel are to be selected randomly.
After the experiment, the whiteness of the two groups will be compared to see the effect of the gel.
Therefore for the experiment to be completely random, 3, 5, and 6 apply.
(b)
For the experiment to be double-blind, the researchers who will evaluate the whiteness and interact with the subjects, and the subjects would not know which subjects received either the whitening gel or the placebo.
The amount you would pay altogether if you borrow $500 for 5 years at
an annual interest rate of 7% is $945.
<h3>How much would you pay altogether?</h3>
The amount you would pay altogether is the sum of the amount borrowed and the interest.
Total value of the debt = interest + amount borrowed
Interest = $700 x 7% x 5 = $245
Total value of the debt = $245 + $700 = $945
False.
In a random sample each member of the group has the same chances to be choosen. A representative sample replicates the characteristcs that you want of the group. Many times you need to make the sampling not random to pick a sample that represents or replicates the group.
