What is the slope of the line passing through the points (0, – 5) and (4, 2)
?
What is the slope?

7/4

Step-by-step explanation:

c) increase

Step-by-step explanation:

As the sample size increases it comes closer to the population size, and so converge to a better result of researcher's analysis.

It means the size of the sample is proportional to the power of their statistical tests.

∴ As the size of the sample increases the power of statistical test increases.

Hence, If a research team increases the sample size for a study, the power of their statistical tests will increases.

Therefore , the correct answer is : c) increase
