Answer:
C)Systematic Random Sample
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this case:
Every kth element(in this exercise 10th) is systematic sample. So the answer is given by option c.
The sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0, the results tend to
<h3>How to interpret Garret studies?</h3>
From the question, we have the following highlights
- The sample size is large enough
- The sample is at random
- Students who have a grade point average of 3.0 - 4.0 sleep for an average of 6.8 hours
- Students who have a grade point average of 2.0–3.0 sleep for an average of 6.4 hours
- There are no outliers
From the above highlights, the sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0
This is because 6.8 is greater than 6.4
This means that Garret's theory about the hours of sleep is correct

Answer:
common ratio:2 2. 18 3.36 4.72 equation: 4.5(
)
Step-by-step explanation:
144=2*2*2*2*3*3 9=3*3
the common ratio would be 2
2. 9*2=18
3. 18*2=36
4. 36*2=72
(check) 72*2=144
0. 9/2=4.5
equation: 4.5()
