Given:
50% of the people that get mail-order catalogs order something.
Determine the probability that exactly 2 out of 10 people getting the catalogs will order something.
If the total number of people is 10, we can calculate the number of people who will order something from the catalogs:
10 * 0.50 = 5 people.
The probability that exactly two out of ten people will order something is:
2/5 = 0.4
Therefore, there is a 40% chance that the exact two people who received the catalogs will order something from it.
Answer:
i) Assigning women at random ensures that the two groups are comparable.
iv) A control group provides a baseline for comparisons to determine treatment effects.
Step-by-step explanation:
(a)
It is pertinent that there two comparable groups. In light of the fact that it will help in making better decisions since there will be some people who have blood pressure as a result of uncontrolled physical characteristics such as anger, positive attitude, lower blood pressure. etc Thus, there is a need to consider two equivalent groups.
(b)
A control group is used as a benchmark for determining the cause and effect of a treatment on a given experimental group. This may be in regard to the social aspect of meeting other individuals involved that make up the physical changes.
