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]

Which data value is farthest from the mean? How far you is this value from the mean? Round to the nearest hundredths. 34,37,48,32,25,34,35,23,33,30.
Answer:
48; 14.90 or 14.9
Step-by-step explanation:
First you have to take the mean of the data set.
In order to do this, we take the sum of all of the data points and then divide them by the number of values like so...
[tex]\frac{34+37+48+32+25+34+35+23+33+30}{10}[/tex]
The answer to this is 33.1.
Now we have to find the value furthest from this value. In order to do this, we are going to take the highest (48) and the lowest value(23). Then we compare their distance from 33.1. After this, we can tell that 48 is further from 33.1 than 23 is.
Then for the second part, 48-33.1 = 14.90 and that is how far the value is from the mean.

1/8 liter of juice. She distributes it equally to 3 students in her tutoring group. What fraction of the juice does each student get?
Answer: 1/24 L
Step-by-step explanation:
[tex]$\frac{1}{8} L \div 3= \frac{1}{8} \div \frac{3}{1}= \frac{1}{8} \times \frac{1}{3}=\frac{1}{24} \quad$ \\\\\begin{aligned}\therefore \text { Each student will get } &\frac{1}{24} L \text { of juice. }\end{aligned}[/tex]

There are 12 corn stalks, 6 tomato plants, 4
squash plants, and 2 cucumber plants in the
garden. What is the probability of randomly
picking a tomato or squash plant from the garden?
O 5/12
O 4/24
O 6/10
O 1/4
The probability of randomly picking a tomato or squash plant from the garden is 5/12.
What is probability ?Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
What is the probability of randomly picking a tomato or squash plant from the garden?Probability = (total number of tomato / total number of fruits) + (total number of squash / total number of fruits)
total number of fruits = 12 + 6 + 4 + 2 = 24
(6/24) + (4/24) = 10/24 = 5/12

What factor could you pull out of 10x AND 5?
2
x
10
5
WILL GIVE BRAINLY
Hi! I hope you're enjoying your day!
The common factor of 10x and 5 is
5.
What is a factor?
It's a number that a number is evenly divisible by.
Example: 2 is a factor of 10, because 10 is evenly divisible by 2.
Also, it may be tempting to say, "Well, 2 is the common factor!"
And that's not true in this case, because 5 isn't divisible by 2.
x is also not a common factor; 5 is a constant, it doesn't have any variables next to it.
Hence, the factor is
[tex]\boxed{\boxed{\bold{5}}}[/tex]
Hope everything is clear.
If you have any questions, please comment.

What happens to the standard error of m as sample size increases?.
Answer:
SEM decreases by a factor of √N
Step-by-step explanation:
The standard error of the mean (SEM) is inversely proportional to the square root of the sample size. As the sample size (N) increases, the SEM is decreased by a factor of √N.
The SEM is the population standard deviation divided by √N for a normal distribution.
