The given inequality is equivalent to
.. |p| < (9 +7)/4
which is represented by the 1st selection.
Answer:
- Determine the null and alternative hypotheses.
- Select a level of significance.
- Draw a random sample, and calculate the sample statistic.
- Decide whether to reject or fail to reject the null hypothesis.
Step-by-step explanation:
The steps that involve testing a hypothesis can be sorted like this:
First, we have to determine the null and alternative hypothesis. This is related directly to the claim we are trying to prove.
Second, we select a level of significance. This depends on how conservative we want to be with the conclusions. We have to do it before evaluating the test statistic, although it is not involved in its calculations.
Third, we draw a random sample, and calculate the sample statistic. This is the core of the hypothesis test, were we use the information of a sample to infer a characteristic of the population.
Fourth and last, with the results of the test statistic, we decide whether to reject or fail to reject the null hypothesis. This leads to the conclusions about the claims.
Hello!
To find the greatest common factor, you must find all the factors of both numbers and see which similar one is the greatest.
27: (1,27) (3,9)
36: (1,36) (2,18) (3,12) (4,9) (6,6)
As you can see the, the greatest common factor is 9.
I hope this helps!
Answer:
The 90% confidence level margin of error for this sample mean is 0.42
Step-by-step explanation:
The Human Resources department conduct a random sample of 30 employees
n = 30
Standard deviation = 
z = 1.645
Formula of 90% confidence level margin of error for this sample mean=
So, margin of error for this sample mean=
So, margin of error for this sample mean=0.42
Hence the 90% confidence level margin of error for this sample mean is 0.42
The correct answer is D hope this helps
