It would most likely be C. Positive association means that the variables will keep increasing.
<span>5 1/2 x 2 1/3</span>
Change your fractions into decimals.
1/2 = 0.5
1/3 = 0.33 (rounded)
5.5 x 2.33 = 12.815
12.815 is your answer
hope this helps

Step-by-step explanation:
Answer:
The study provided uses a Cluster sampling method.
Step-by-step explanation:
The researcher first selects all the schools in the district.
Then he samples 5 schools from the entire district using a random number generator.
Then the researcher interviews every teacher from the 5 schools selected.
This is an example of cluster sampling.
In a Cluster sampling method, the researchers first divide the entire population into homogeneous groups, then selects a random sample of groups form the population. Then they select a random sample from each group selected.
If the researcher samples the entire groups selected then this is the case of one-stage cluster sampling and if they select a random sample of fixed size from each group selected then this a case of two-stage sampling.
Thus, the study provided uses a Cluster sampling method.
