ANSWER:
EXPLANATION:
A simple random sample of size has mean and standard deviation. Construct a confidence interval for the population mean. The parameter is the population The correct method to find the confidence interval is the method.
The sample size is not given. Mean and Standard Deviation are not given.
To construct a confidence interval for the population mean, first find out the margin of error of the sample mean. This is why you need a confidence interval. If you are 90% confident that the population mean lies somewhere around the sample mean then you construct a 90% confidence interval.
This is equivalent to an alpha level of 0.10
If you are 95% sure that the population mean lies somewhere around the sample mean, your alpha level will be 0.05
In summary, get the values for sample size (n), sample mean, and sample standard deviation.
Make use of a degrees of freedom of (n-1).

Step-by-step explanation: algebra
Answer:
f(x)=-|x|
Step-by-step explanation:
We have been given a graph of f(x) which resembles with the graph of function g(x) where g(x)=|x|.
It says that graph is flipped over the x-axis.
Now we have to find about which of the following choice correctly describes the given graph.
We know that |x| means absolute value of x so that means g(x)=|x| is absolute function in shape of V.
We know that flipping over x-axis can be done by changing f(x) into -f(x).
<u>Hence correct answer is choice D) F(x)=-|x|</u>
On the graph we have points x:y of
3:5
6:10
12:20
which are all in the ratio 3:5, a slope of 5/3.
3:5=9:y
y=9×5/3 = 15
Answer: C (9,15)
