Answer:
3. the sampling distribution of the sample mean is normally distributed.
5. the value of the sample mean varies from sample to sample.
Explanation:
We develop confidence interval for population mean because
a. the sampling distribution of the sampling mean is normally distributed. For us to do this we must first ensure that the sample mean is large enough
B. The value of the sample mean is not the same for all samples it varies from sample to sample. Therefore it it is better that an internal is given with the probability that the parameter falls into it.
Answer:
The primary difference between product markets and factor markets is that factors of production like labor and capital are part of factor markets and product markets are markets for goods. ... Anything used in making a finished product—labor, raw materials, capital, and land—make up a factor market.

Journal Information
This distinguished journal was founded and edited for more than 20 years by the late Harold Marcus, whose energy and dedication to the scholarly study of Ethiopia and its neighbors in the Horn of Africa inspired several generations of students and scholars throughout the world. While Northeast African Studies will bring some changes in focus and format, the editors remain committed to the high standards of research, writing, and production that the original journal championed.
Frm :-
Jeremy is involved in reflection
.
Option B
<u>Explanation:
</u>
It represents the paraphrasing process which reflects both the speaker's thoughts and words. The goal of reflection is:
Let the presenter ' hear ' his own words and reflect on what they suggest and sound. To convince the presenter that you see the universe as they see it and do the best to understand its messages.
In order to encourage them to speak.
Reflecting doesn't really involve asking the questions; introduce a new topic, or contributing a conversation in a different direction. Speakers are encouraged to learn because they can not only feel heard, but can also concentrate their thoughts. In effect, it allows them to think and encourage them to speak more.
This problem is actually under the subject of Mathematics, particularly, Algebra. For work problems, you can use a convenient technique of dimensional analysis. This is done by multiplying units of measurement, then cancelling out like terms in order to come up with the units of the final answer. For this problem, the total amount of liters is 2,100. So, the equation would be
Volume of Kelly's family + Volume of Stewart's family = 2,100
However, we are only given the rates for each family in liters per hour. To come up with the final answer with a unit of measurement in Liters, we must multiple the rate of L/hour with the individual time. Let x be the time Kelly's sprinkler was used, and y for Stewart's family.
(20 L/h)(x hours) + (40 L/h)(y hours) = 2,100
This is the first equation. The second equation is the total time.
x + y = 65 hours
Rearranging the equation, y = 65 - x. Let's substitute this to the first equation.
20x + 40(65-x) = 2,100
Solving for x, then substituting it to the second equation to obtain y,
x = 25 hours
25 + y = 65
y = 40 hours.
Thus, Kelly's sprinkler was used for 25 hours, while Stewart's sprinkler was used for 40 hours.
