The probability distribution of the population data is called the (1) table 7.2 in the text provides an example of it. the probability distribution of a sample statistic is called its (2) table 7.5 in the text provides an example it.
a. probability distribution
b. population distribution
c. normal distribution
d. sampling distribution

The first answer is a letter c - normal distribution. The normal distribution is the most significant and most generally used distribution in statistics. It is also known as the Gaussian or standard normal distribution, is the probability distribution that plots all of its values in an even fashion, and most of the results are positioned around the probability's mean. Values are equally likely to plot either above or below the mean. And the second answer is letter d - sampling distribution. In statistics, it is the probability distribution of a given statistic centered on a random sample. Sampling distributions are significant in statistics because they deliver a major simplification to the statistical inference.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
