Answer:Simple random sample

Step-by-step explanation:

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group.

NOTE:

No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied.

What is the solution for the =.

liq [111]

Answer:

solution for n is $\frac{-13}{4}$

Step-by-step explanation:

Given an equation containing one variable n.

The equation is as follows:

$\frac{-5}{2} =\frac{3}{4} +n$

To solve for n we can subtract 3/4 from both the sides

The result is

$\frac{-5}{2} -\frac{3}{4} =n\\Take LCD as 4\\\\frac{-10-3}{4} =n$

Verify:

Substitute the answer in the given equation.

$\frac{-5}{2} =\frac{3}{4} -(\frac{13}{4} )$

Both sides equal thus proving our correctness of answer.
