Answer: Standard error.
Step-by-step explanation:
If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean ![[tex]\overline{x}](https://tex.z-dn.net/?f=%5Btex%5D%5Coverline%7Bx%7D)
[/tex] is known as standard error which depends on population standard deviation 
and the sample size (n).
It measure the variability in the sample statistics that happens by chance.
Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.
Answer:
Below.
Step-by-step explanation:
A = 1/2bh for a triangle.
36 = 1/2b(12)
36 = 6b

b = 6
A 99% confidence interval for the population mean of high school students that take the bus to school every day is b) ci=(44.34%, 54.43%)
We need to find the 99% confidence interval for the population mean of high school students that take the bus to school everyday
A confidence interval is a range of estimates for an unknown parameter. The confidence interval is calculated at the specified confidence level; the most common is the 95% confidence level, but sometimes other levels are used, such as 90% or 99%.
The confidence interval of proportions is given by:
π ± z √(π (1-π) /n)
π is the sample proportion.
z is the critical value.
n is the sample size.
For 99% confidence interval the value of z is 2.58
π = 321/650
The confidence interval is given by
=321/650 ± 2.58 √( (321/650) × [ 1 - (321/650) ] ÷ 650)
= (0.493846 ± 0.050594)
=(0.4434 , 0.5443)
=(44.34 % , 54.43 %)
Hence a 99% confidence interval for the population mean of high school students that take the bus to school every day is ci=(44.34%, 54.43%)

<u>Given</u>:
The measure of ∠EGF is 51°
We need to determine the measure of ∠EHF
<u>Measure of ∠EHF:</u>
By inscribed angle theorem, we know that, "if two inscribed angles of a circle intercept the same arc then the angles are congruent".
Applying the theorem, we have that the two inscribed angles of a circle intercepting the same arc are ∠G and ∠H
Then, the two angles are congruent.
Thus, we have;
∠G ≅ ∠H
Therefore, the measure of ∠G = ∠H = 51°
Hence, the measure of ∠EHF = 51°
I strongly believe that the answer is d. But I really believe that is the answer
