Answer:
The margin of error is ![ME = 2.2962](https://tex.z-dn.net/?f=ME%20%3D%202.2962)
Step-by-step explanation:
From the question we are told that
The number of student is ![n = 500](https://tex.z-dn.net/?f=n%20%3D%20500)
The highest amount is
$200
The lowest amount is
$75
The sample mean is
&140
The Standard deviation of this set is mathematically evaluated as
![s = \frac{A-B}{4}](https://tex.z-dn.net/?f=s%20%3D%20%20%5Cfrac%7BA-B%7D%7B4%7D)
Substituting values
![s = \frac{200-75}{4}](https://tex.z-dn.net/?f=s%20%3D%20%20%5Cfrac%7B200-75%7D%7B4%7D)
![s = 31.25](https://tex.z-dn.net/?f=s%20%3D%2031.25)
The margin of error (ME) is mathematically evaluated as
![ME = t_{n-1}__{\alpha }} * \frac{s}{\sqrt{n} }](https://tex.z-dn.net/?f=ME%20%3D%20%20t_%7Bn-1%7D__%7B%5Calpha%20%7D%7D%20%2A%20%20%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%20%7D)
Where
is the critical value for
i.e the significance level
From the critical value table this is
So
![ME = 1.649 * \frac{31.25}{\sqrt{500} }](https://tex.z-dn.net/?f=ME%20%3D%20%201.649%20%20%2A%20%20%5Cfrac%7B31.25%7D%7B%5Csqrt%7B500%7D%20%7D)
![ME = 2.2962](https://tex.z-dn.net/?f=ME%20%3D%202.2962)
Answer:
Simple the area is 88
Step-by-step explanation:
Answer:
Step-by-step explanation:
Bill=3475
Interest=1.5%
Total payment made=3475+3475x1.5/100
=3475x101.5/100
=3527.125$ is the total payment (answer)
Answer: 9 remainder 2
Explanation: 9 is the closest 6 can get to 56 without going over. Since 9•6=54, and 56-54=2 , 2 is the remainder.
