A. it is very small.
B. It is not randomly chosen.
C. It results in incorrect predictions.
D. It does not accurately represent the population.
Answer:
i think it is B
Step-by-step explanation:
bias means you have an opinion on something and you make choices on it so a biased sample would not randomly chosen
The correct option is:
D.) It does not accurately represent the population.
What is sampling?In statistical analysis, sampling is the procedure by which researchers select a specific number of observations from a larger population. The sample strategy will depend on the sort of study being done, although it may involve systematic sampling or just plain random sampling.
It is a common statistics practice, when we want to study something from a population, we find a sample, which is a group of members of this population. The sample has to be representative of the population, that is, it has to involve all of its groups. If it does not involve all the groups, it is not an accurate representation of the population, and is called biased.
Hence, option C is correct.

What is the top-selling board game?
In what aisle are the board games located in the local store?
How many board games require a deck of cards to play?
How many board games have you played in the past month?
Answer:
The question that is a statistical question would be:
"How many board games have you played in the past month?"
Step-by-step explanation:
A statistical question is defined as a question that can be answered by collecting data that vary. Basically, it is a question that can be surveyed. The question, "How many board games have you played in the past month?", is the only one that is statistical because multiple different answers can be given to this question.

Step-by-step explanation:
The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)
1.5
2.2
3.0
4.6
Answer:
The number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders is:
3.0
In order to find the variability between the two sets we divide the mean absolute deviation of the first set of data by the mean absolute deviation of the second set of the data.
The MAD of first set of data is: 1.2
and MAD of second set of data is: 0.4
Hence, let n be the number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders.

so for the first one, y=4x
meaning y = 4 times x
if y=1, x=4. y=2,x=8 y=3,x=12 etc..
same concept for the other ones.
y=x+6
x=1 then 1+6 = 7, so y=7
x=2 then 2+6 = 8, so y=8
etc

y = 4x
y = 4(1)
y = 4
(1, 4)
y = 4x
y = 4(2)
y = 8
(2, 8)
y = 4x
y = 4(3)
y = 12

Plot the points, and draw the line. See the first attached graph.
8. Let's put points in this equation, 1, 2, and 3 will do.
y = x + 6
y = 1 + 6
y = 7
(1, 7)
y = x + 6
y = 2 + 6
y = 8
(2, 8)
y = x + 6
y = 3 + 6
y = 9
(3, 9)
Plot the points, and draw the line. See the second attached graph.
9. Let's put points in this equation, 1, 2, and 3 will do.
y = 2x + 1
y = 2(1) + 1
y = 2 + 1
y = 3
(1, 3)
y = 2x + 1
y = 2(2) + 1
y = 4 + 1
y = 5
(2, 5)
y = 2x + 1
y = 2(3) + 1
y = 6 + 1
y = 7
(3, 7)
Plot the points, and draw the line. See the third attached graph.
