Hi! I am here! I need more letters lol but ya I am here
The amount of money Kim, maneet and Sutopa have is $115.6, $97.6 and $73.2 respectively.
<h3>Equation</h3>
- Kim = x
- Maneet = x - 18
- Sutopa = 3/4(x-18)
- Total = $286.40
x + (x - 18) + 3/4(x-18) = 286.40
x + x - 18 + 3/4x - 13.5 = 286.40
2 3/4x = 286.40 + 13.5 + 18
11/4x = 317.9
x = 317.9 ÷ 11/4
= 317.9 × 4 / 11
= 1,271.6 / 11
x = $115.6
So,
Kim = x
= $115.6
Maneet = x - 18
= 115.6 -18
= $97.6
Sutopa = 3/4(x-18)
= 3/4(97.6)
= $73.2

Answer:
The 95% confidence interval for the population mean is between 25.86 and 28.14.
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.
The lower end of the interval is the sample mean subtracted by M. So it is 27 - 1.14 = 25.86
The upper end of the interval is the sample mean added to M. So it is 27 + 1.14 = 28.14
The 95% confidence interval for the population mean is between 25.86 and 28.14.
