If the outliers were included in the data, the box plot would be significantly skewed.

Step-by-step explanation:

Outliers are the extreme values of the data.
mean is averaging it tries to balance between extreme values.
Median is mid-point of data.
Skewness it the distribution of data Symmetric mean=median=mean.
Asymmetric is extreme values distribute the data either right or left.
If mean is less then median it is left skewed, if mean is greater then median it is right skewed.
Whiskers show the range of the data.

If the sample size is multiplied by 4, what happens to the standard deviation of the distribution of sample means?

Feliz [49]

Increasing the sample size by a factor of 4 or multiplying it by 4 is equal to increasing the standard error by 1/2. Therefore, the interval will be half as varied. This also works almost for population averages as lengthy as the multiplier from the t-curve doesn't modify much when increasing the sample size.

If IM is reflected across the x-axis and then translated along the vector <4, 1>, in

taurus [48]

Answer:

Final image L"M" will lie in the fourth quadrant.

Step-by-step explanation:

Coordinates of the ends of segment LM,

L → (-3, 4)

M → (-3, 2)

Rule to reflect a point across x-axis is,

(x, y) → (x, -y)

By this rule, coordinates of the image point of L and M will be,

L(-3, 4) → L'(-3, -4)

M(-3, 2) → M'(-3, -2)

Further these image points are translated along the vector <4, 1>

Rule for this translation will be,

(x, y) → (x + 4, y + 1)

Now the image points of the points L' and M' will be,

L'(-3, -4) → L"(-3 + 4, -4 + 1)

→ L"(1, -3)

M'(-3, -2) → M"(-3 + 4, -2 + 1)

→ M"(1, -1)

Therefore, final image L"M" will lie in the fourth quadrant.
