Answer:
mass, location, and force from earth
Step-by-step explanation:
Using the <em>normal distribution and the central limit theorem</em>, it is found that the power of the test is of 0.9992 = 99.92%.
<h3>Normal Probability Distribution</h3>
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .
In this problem:
- The mean is .
- The standard deviation is .
- A sample of 30 is taken, hence .
The power of the test is given by the probability of a sample mean above 8, which is <u>1 subtracted by the p-value of Z when X = 8</u>, so:
By the Central Limit Theorem:
has a p-value of 0.0008.
1 - 0.0008 = 0.9992.
The power of the test is of 0.9992 = 99.92%.

It should by the answer but if not sorry
Answer:
(X,Y)
(0,6)
Add them all up .
100,000 + 4,000 = 104,000
800 + 5 = 805
104,000 + 805 = 104,805
Standard Form : 104,805
