THIS IS THE COMPLETE QUESTION BELOW;
The weekly salaries of sociologists in the United States are normally distributed and have a known population standard deviation of 425 dollars and an unknown population mean. A random sample of 22 sociologists is taken and gives a sample mean of 1520 dollars.
Find the margin of error for the confidence interval for the population mean with a 98% confidence level.
z0.10 z0.05 z0.025 z0.01 z0.005
1.282 1.645 1.960 2.326 2.576
You may use a calculator or the common z values above. Round the final answer to two decimal places.
Answer
Margin error =210.8
Given:
standard deviation of 425
sample mean x=1520 dollars.
random sample n= 22
From the question We need to to calculate the margin of error for the confidence interval for the population mean .

A:
Min is 15
LQ is 23
Median is 36
UQ is 38
B:
IQR is 38 minus 23, or 15, I guess that the data is not very consistent and it is spread out?
C:
Min is calculated by looking at the end of the far left line
LQ is the far left of the box
Median is the line inside the box
UQ is the the far right of the box
IQR is UQ subtract LQ
Answer:
4a³+3a-3
Step-by-step explanation:
You can solve this by combining like terms. Add the numbers with the correct exponents together.
-a³+5a³
4a-a
Thus, the answer is
4a³+3a-3
Answer:
The expanded form of 1.2*10^9 is 1400000000
I'm not very sure what you mean but I have found two solutions.
Solution No.1:
1400000000 - 7000 = 1399993000
Solution No.2:
Let's say the variable is "x"
7000 * x = 1400000000
x = 200000
Hope this helped! :)
Answer:
Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
If the three are to be next to each other,
First, we arrange the three
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
So, the total arrangement, when they have to be next to one another is:
The probability is:
Expand
Express as percentage
