Formula of volume of a cylinder = πr²h
V = πr²(2)
32π= 2πr²
r² = 16 Divide by 2π
r = 4 Square root both sides
<em>The radius is 4) 4</em>

Answer:
1.9
Step-by-step explanation:
The MAD is found by <em>finding the mean, then finding how far each number is to the mean, then finding the mean of that.</em>
The mean is: <em>(1 + 8 + 3 + 1 + 3 + 3 + 7 + 5 + 1 + 3)/10</em> = 35/10 = <em>3.5</em>
The distances of all of the numbers is <em>(absolute value of the difference between 3.5 and the number) </em>: <em>2.5, 4.5, 0.5, 2.5, 0.5, 0.5, 3.5, 1.5, 2.5, 0.5</em>
The mean of those is: <em>(2.5 + 4.5 + 0.5 + 2.5 + 0.5 + 0.5 + 3.5 + 1.5 + 2.5 + 0.5) /10</em> = 19/10 = 1.9
Answer:
False. Is the inverse process.
See explanation below.
Step-by-step explanation:
We need to remember two important concepts:
A parameter, is a quantity or value who describe a population desired, for example the population mean
or the population standard deviation ![\sigma](https://tex.z-dn.net/?f=%5Csigma)
A statistic, is a quantity or value who represent the information of the sample data, for example the sample mean
or the sample deviation ![s](https://tex.z-dn.net/?f=%20s)
Based on this we can analyze the statement:
"Inferential statistics involves using population data to make inferences about a sample"
False. Is the inverse process.
If we know the population data then we indeed have parameters and we don't need to do any type of inference in order to estimate these parameters with the statistics.
What we do generally is use the information from the sample in order to obtain statistics representative of the population with the aim to estimate the parameters unknown of the population
