Answer:
The correct selections are:
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups.
C) A placebo is not being used
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call.
Step-by-step explanation:
What this question requires from you, is to identify the correct characteristics of the study described. Let us explain why each of the selections was made.
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups: The purpose of the study is to determine the difference in the effectiveness of two methods of fundraising. Therefore at the end of the study, the average total amount raised from each group will be compared to determine which was more effective.
C) A placebo is not being used: Placebos are sham treatments used in a control group without their knowledge. The placebos do not produce any effect similar to the results anticipated the actual treatment. Here, no group is given sham treatment, there is no "control" group given placebos hence placebos are not used.
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call: To remove any form of bias in the study, the selection of the groups is done at random, and the number of participants in each group is the same, so as to maintain uniformity during the comparison.
<h2>Problem Solving</h2>
Recipe A makes 5 dinner rolls using 1 c of flour. Recipe B makes 24 rolls using 7 1/2 c of flour. which recipe requires the most flour per roll
- To know which recipe requires the most flour per roll, let's convert fraction to decimal.
before that let's convert the recipe B from mixed fraction to decimal then, the total is the numerator and make 24 as the denominator.
How do we convert fraction to decimal?
- Divide the numerator by the denominator.
- Then, add the whole number. ( if it is mixed fraction)
Recipe B
Recipe B
Recipe A
Recipe A
Recipe B is great than Recipe A
Therefore, Recipe B requires the most flour per roll.
