The standard deviation of a point estimator is the <u>standard error.</u>
"The point estimate is used to estimate the exact value of any parameter. For example, an internet poll says that 45% of Americans are concerned for the environment."
"Point estimates is a good measure but the problem with this parameter is that the sample of the statistics may vary so that there is a chance of sampling error."
"As the researcher is unable to presume that closeness of the sample statistics parameter with respect to the parameter so researcher refers to calculate the standard error instead of point estimate."

= is parallel lines because they are in line with each other. Hope I helped :D
Answer:
3/7
Step-by-step explanation:
21w - 21 = -12
21w = -12 +21
21w = 9
w = 9/21
i.e w= 3/7
Answer:
1.8 in.
Step-by-step explanation:
Hi there!
<u>1) Determine the radius of the base</u>
where r is the radius of the base and h is the height of the cone
Plug in the known values (h=4.2, V=3.6)
Isolate r; divide both sides by 4.2
Multiply both sides by 3
Divide both sides by π
Take the square root of both sides
<u>2) Determine the diameter</u>
Now that we have the radius, to find the diameter, multiply r by 2:
Therefore, the diameter is 1.8 in. when rounded to the nearest tenth.
I hope this helps!
