You!

which of the following describes the probability distribution below?

a.) the median is greater than the mean, and the majority of the data points are to the left of the mean.
b.) the median is greater than the mean, and the majority of the data points are to the right of the mean.
c.) the mean is greater than the median, and the majority of the data points are to the left of the mean.
d.) the mean is greater than the median, and the majority of the data points are to the right of the mean.

(it is not letter "a" i know that for sure! )

From the graph shown we can describe the distribution as follows:
Majority of the data points are to the right of the mean, this implies that the median is greater than the mean of the data, thus we can conclude that the correct answer is:
B] The median is greater than the mean, and the majority of the data points are to the right of the mean.

Option: B is correct.

( B.) The median is greater than the mean, and the majority of the data points are to the right of the mean ).

Step-by-step explanation:

With the help of the data:

the mean is calculate as:

Mean=∑x×P_x

From the table we have:

x P_x xP_x

1 0.1 0.1

2 0.15 0.3

3 0.2 0.6

4 0.45 1.8

5 0.1 0.5

∑xP_x=3.3

Hence the Mean of the data is 3.3

Also the median is the central tendency of the data or the central value.

Also from the graph we could see that the majority of the data points are to the right of the mean.

Hence, Median will lie to the right of the mean.

Hence, option: B is correct.

( B.) The median is greater than the mean, and the majority of the data points are to the right of the mean )

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a). here, that comes to

)

x = = 1. f(1) = 1^2 - 2(1) - 8 = - 9. vertex is at (1, -9).

2(1)

find another point on the curve: let x=0, for which y=-8. then (0, -8) is on the curve. plot the vertex and this point and draw a smooth parabola thru both.

hope this
