Please see picture below.
Step-by-step explanation:
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.
Answer:
44580 inches
Step-by-step explanation:
Given, D (diameter)= 22 inches
Therefore, r (radius)= 22/2= 11 inches
Volume= 
×π×r³
=×3.14×22×22×22
=44579.626 inches
=44580 inches
Answer:
Commutative property
Step-by-step explanation:
- Commutative property states that no matter how the addens are placed, the result of the operation (sum) remains the same.
- For <u>example</u>, given three numbers a, b and c, the result of
. - Then, when you are solving a sum, the order of the elements does not matter. If we want to see this numerically, with an other example:
.
