A simple random sample of n measurements from a population is a subset of the population selected in a manner such that which of

Ierofanga [76]

Answer:

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.

Step-by-step explanation:

Simple random sampling:

It is a type of probabilistic sampling.
It is an unbiased representation of population.
The probability of selection is equal for every observation.
A sample is taken in such a way that each member has an equal probability of being selected.
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.
Thus,the correct interpretation is given by,

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.

c) The simplest method of selection is used to create a representative sample.

The statement is false.

There is no pattern or technique used for selection. The selection is purely random.

d) Each subset of the population has an equal chance of being included in the sample.

The statement is false.

Each object of the population has an equal chance of being included in the sample. and not each subset.

e) Every sample of size n from the population has a proportionally weighted chance of being selected.

The given statement is false.

The answer would be twenty five percent because four and one half is equal to seventy-five percent and one hundred minus seventy-five would be twenty-five.

Answer:

The equation of line passes through $(4,-1)$ and perpendicular to the graph $y=\frac{7}{2}x-\frac{3}{2}$ is $y=\frac{-2x}{7}+\frac{1}{7}$

Step-by-step explanation:

Given point is $(4,-1)$ and equation of line is $y=\frac{7}{2}x-\frac{3}{2}$

Let the slope of line that passes through point $(4,-1)$ is $m_1$

And slope of line $y=\frac{7}{2}x-\frac{3}{2}$ is $m_2=\frac{7}{2}$ . As it is in the form of $y=mx+c$

We know the relation between slope of perpendicular line are given by

$m_1\times m_2=-1\\And\ m_1=\frac{-1}{m_2}$

So, the slope $m_1=\frac{-1}{\frac{7}{2}}=\frac{-2}{7}$

Now, we can write the equation of line having point $(4,-1)$ and slope $\frac{-2}{7}$

$(y-y_1)=m(x-x_1)\\\\(y-(-1))=\frac{-2}{7}(x-4)\\\\y+1=\frac{-2x}{7}-(\frac{2\times -4}{7})\\ \\y+1=\frac{-2x}{7}+\frac{8}{7}\\\\y=\frac{-2x}{7}+\frac{8}{7}-1\\\\y=\frac{-2x}{7}+\frac{8-7}{7}\\\\y=\frac{-2x}{7}+\frac{1}{7}$

So, the equation of line passes through $(4,-1)$ and perpendicular to the graph $y=\frac{7}{2}x-\frac{3}{2}$ is $y=\frac{-2x}{7}+\frac{1}{7}$
