What design principle is stressed for experiments or observational studies?
Choose the correct answer below.
A. Using dependent samples with paired data is generally better than using two independent samples.
B. When using paired data, keep the sample very small in order to keep the data manageable.
C. The methods for dependent samples can be used for any matched pairs.
D. Using two independent samples is the best choice for accurate results.

b

Step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
