Answer:
The minimum sample size required to create the specified confidence interval is 2229.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
What is the minimum sample size required to create the specified confidence interval
This is n when 
Rounding up
The minimum sample size required to create the specified confidence interval is 2229.
Answer:
Step-by-step explanation:
Given
Required
Express in standard form
To do this, we simply reorder the terms of the polynomial in descending order of power.
So, we have:
Answer:
(This is a example since you don’t have anything to round to)
Example Answer if the radius is 4 - 50.24
Step-by-step explanation:
Example Radius : 4
Area : 3.14
We have the mulitiply 3.14 times The Example Radius 2 times because The diameter of a circle is 2 times its radius.
( 3.14 x 4 x 4) 50.24
If you know the diameter, it’s a half or 1/2 as large.
Therefore, if the radius was 4, it would be 50.24.
Youre welcome :)
Answer:
5.4 > x > 2.8
Step-by-step explanation:
Sum of two sides is always greater than the third side
Case1 :
4.1 + 1.3 > x
5.4 > x
Case2:
4.1 + x > 1.3 or 1.3 + x > 4.1
x > 1.3 - 4.1 or x > 4.1 - 1.3
x > - 2.8 or x > 2.8
Note that it is obvious x is not -ve so neglect -2.8. x > 2.8
Hence,
5.4 > x > 2.8
