A simple random sample of size n is drawn from a normally distributed population, and the mean of the sample is x Overbar, while the standard deviation is s. What is the 99% confidence interval for the population mean? Use the table below to help you answer the question. Confidence Level 90% 95% 99% z*-score 1. 645 1. 96 2. 58.
Using the z-distribution, as we have the standard deviation for the population, it is found that the 99% confidence interval for the population mean is given by:
[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm z\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.s is the standard deviation for the population.99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.58[/tex].
The other parameters are symbolic, hence the interval is given by:
[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]

I hope this helps you:)I have no clue how I’m supposed to do this…
Answer:
Step-by-step explanation:
We will need to rewrite the Pythagorean Theorem
A^2 + B^2 = C^2
Substitute. tIn this case:
18^2 + x^2 = 82^2
Subtract 18^2
x^2 = 82^2 - 18^2
In order to get x alone, take the root:
x = sqrt(82^2 - 18^2)
And solve:
x = 80

You start at (0, 8). You move down 7 units and right 8 units. Where do you end?
========================================================
Explanation:
The "move down 7" means the y coordinate 8 becomes 8-7 = 1
We subtract 7 from the y coordinate.
The "move right 8 units" means we add 8 to the x coordinate to get 0+8 = 8
Therefore, the point (0,8) moves to (8, 1)

D. 108/100
WILL GIVE BRAINLIEST
Answer: B. 8/100
Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:
5/10 * 10 = 50/100
Now, we can subtract 50/100 from 58/100 to find the unknown fraction:
58/100 - 50/100 = 8/100
This gives us an answer of,
B. 8/100

Find the values of x, y, and z. Round to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
The value of x is 15, y is 5 and z is 17 units in the given triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
First let us find value of y
We know that hypotensue / leg = leg/y
20/10 = 10/y
Apply cross multiplication
20y=100
y=5
Now let us find x value
20-y=x
20-5=x
x=15
The altitude is √5.15= √75
=8.6
Now by pythagoras theorem, we find value of z
x²+75 = z²
15²+75 = z²
225+75= z²
300= z²
z=17.3
Hence, the value of x is 15, y is 5 and z is 17 units in the given triangle.
