Find the 99% confidence interval for the population mean when the population standard deviation is

Mathematics
1 answer:
trapecia [35]2 years ago
4 0

The 99% confidence interval for the population mean is 6± 2.443

<h3>Confidence interval</h3>

The formula for calculating the confidence interval is expressed as:

CI = x± z(s/√n)

GIven the following parameters

x = 6

s = 3

n = 10

z score at 99% = 2.576

Substitute into the formula to have:

CI = 6± 2.576(3/√10)

CI = 6± 2.443

Hence the 99% confidence interval for the population mean is 6± 2.443

Help me please thank you

After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9

2-9= -7

therefore, f(x)= -7

if x=1, then the f(x) must be Y

<u><em>therefore, your answer should be y= -7</em></u>

Write a system of linear equations that has the ordered pair as its solution (3,5)
ololo11 [35]
An easy way to do this is by using the simplest equations you can:

x + y and x - y

(3, 5) is (x, y). all you have to do is plug those into your equations and get a result, so:

x + y = 8
(because 3 + 5 = 8)
x - y = -2
(because 3 - 5 = -2)

and those can serve as your system of equations. 

you can check it by solving by substitution:
x - y = -2
x + y = 8

solve one of the equations for a single variable:
x = y - 2

plug it into the second equation:
(y - 2) + y = 8
y - 2 + y = 8
2y - 2 = 8
2y = 10
y = 5

then plug that result back into the equation:
x + y = 8
x + 5 = 8
x = 3
