The correct answer would be 23% because 28+34+40+22=124, and if you do the butterfly method you would multiply 28 by 100 and you get 2800 then divide that by 124 and you get 22.5% but since you have to round to the nearest percent it's 23%
True, as sample size n becomes large, sample mean of a sample from a population is the same as the population mean.
<h3 /><h3>What is Sample mean?</h3>
The statistic known as the sample mean is created by arithmetically averaging the values of a variable in a sample. The sample mean is an estimator of the expected value if the sample is taken from probability distributions with a common expected value.
The sample mean of a population sample approaches the population mean as sample size n increases.
A sample that is more representative of the population and that has a bigger size is also a better sample to employ for statistical analysis. Even if the difference between the experiment and control group is lower as the sample size increases, it is simpler to spot the difference.
In other words, The sampling distribution's mean equals the population mean when there are "infinite" numbers of subsequent random samples taken at random. Each sampling distribution's variability diminishes as sample size rises, making the distributions more and more leptokurtic.

Answer:
option D
Step-by-step explanation:
Given in the question are 4 number
5√1/3 -
2 -
9 +
A Complex Number is a combination of a Real Number and an Imaginary Number
<h3>Example </h3>
a + ib
where a is real number
b is imaginary number
i is 'lota' which is √-1
<h3>So according to the definition above </h3>
is complex number in which
is real part
= is the imaginary part
Answer:
-2,1 I am pretty sure that is correct.
