Outliers can sometime be observed in a data set and when they are, they are C. not near the main cluster of data.

An outlier in a dataset:

Is far from the main cluster of data Affects the mean by disproportionately pulling it up or down Is usually one of the highest or lowest value in the set

An example of a data set with an outlier is:

4, 7, 9 , 12, 80, 108

The outliers in the above are 80 and 108 because they are quite far away from the rest of the dataset.

In conclusion, outliers are usually not near to the main cluster of data.

A. This is not the correct answer because an outlier is observed and not a false data point (assuming the observation was done correctly). So we can rule out choice A.

B. An outlier does affect the mean. For example, if you have an outlier that is too high compared to the main cluster of values, then the mean will be larger than it should be. This is why we can rule out choice B

C. This is the correct answer. The outlier value is some value far removed from the main cluster or group of data values. It can be really high or really low.

D. This may seem like the answer, but not all outliers are the min or max. Its possible to have an outlier that is smaller than another outlier. So this is why we can rule out choice D.

In summary, the only answer is choice C

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

Bwill make the inequalities y < 2x + 1 and y> -x- 2 true. o a. region b o b. region c o c. r
