A statistical program is recommended. A random sample of soil specimens was obtained, and the amount of organic matter (%) in th

e soil was determined for each specimen, resulting in the accompanying data. 1.125.090.971.594.600.320.551.45 0.164.471.203.505.024.675.222.69 3.963.173.032.210.694.473.311.17 0.701.171.572.621.662.05 The values of the sample mean, sample standard deviation, and (estimated) standard error of the mean are 2.480, 1.616, and 0.295, respectively. Does this data suggest that the true average percentage of organic matter in such soil is something other than 3%

Answer:

The values of the sample mean, sample standard deviation, and (estimated) standard error of the mean are 2.484, 1.611, and 0.294, respectively. Does this data suggest that the true average percentage of organic matter in such soil is something other than 3%? Carry out a test of the appropriate hypotheses at significance level 0.10. [Note: A normal probability plot of the data shows an acceptable pattern in light of the reasonably large sample size.]

Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.)

Answer:

1/8

Step-by-step explanation:

To simplify the expression √3/√8, we can first simplify the square root terms by finding the prime factorization of each number under the square root. The prime factorization of 3 is 3, and the prime factorization of 8 is 2 * 2 * 2.

We can then rewrite the square root terms as follows:

√3/√8 = √(3) / √(2 * 2 * 2)

Next, we can use the property of square roots that says that the square root of a number is equal to the square root of each of its prime factors. This means that we can rewrite the square root term as follows:

√(3) / √(2 * 2 * 2) = √(3) / √(2) / √(2) / √(2)

Since the square root of a number is the same as the number itself, we can simplify the expression further by removing the square root symbols from the prime numbers 2:

√(3) / √(2) / √(2) / √(2) = √(3) / 2 / 2 / 2

Finally, we can use the rules of division to simplify the expression even further:

√(3) / 2 / 2 / 2 = √(3) / (2 * 2 * 2)

Since any number divided by itself is equal to 1, we can simplify the expression one last time to get our final answer:

√(3) / (2 * 2 * 2) = 1/2 * 1/2 * 1/2 = 1/8

Therefore, the simplified form of the expression √3/√8 is 1/8.

What is the geometric mean of 30 and 6
Alik [6]
Since we have 2 numbers, we'll be square rooting.

All we have to do to find the mean is multiply & square root the products.

30 × 6 = 180

\sqrt{180} = 13.42

You can use the same process and check my answer if you'd like; I rounded the square root, so you may get a different answer.
