Enter each data set into the statistics calculator. make note of the histogram, mean, and median of each data set. a = {10, 12, 12, 6, 8, 5, 4, 10, 8, 10, 12, 12, 6} b = {8, 8, 8, 7, 9, 7, 9, 10, 6, 8} which statements are true about the data sets? check all that apply. set a is symmetrical. set b has the same mean and median. set b is right skewed. set a is left skewed. the median of set a is larger than the mean of set a.

Skewed data set is non-symmetrical, and is biased over one side. For the given data sets, the true statements are:

Data set which has symmetry in values vs frequency graph(histogram) for some vertical axis, is called symmetrical data set.

When the data set is not symmetrical and its graph is leaning on some side(left side or right side), then such data set is called skewed data set(skewed left, or right, respectively).

Median of right skewed data is higher than symmetric data with same range, and vice versa for left skewed data(ie smaller median than symmetrical data).

For the symmetrical data(specially bell distribution), the mean, median and mode lie on same point(the point over which the vertical line of symmetry lies).

Arranging the data sets with their values to frequencies:

For set A:
4 1

5 1

6 2

8 2

10 3

12 4

For set B:

6 1

7 2

8 4

9 2

10 1

The histogram plotted for set A will be leaning on right, as frequency increases as value increases. Thus, it is right skewed.

The histogram plotted for set B will be symmetric about value 8, as frequency before value 8 and after value 8 are symmetric(see the pattern 1, 2, 4,2,1 )

And therefore, for the given data sets, the true statements are:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
