Answer:
B
Step-by-step explanation:
No because the arcs do not have the same measure. The measure of one arc is 142 and the other is 140.
We want to find the median for the given density curve.
The value of the median is 4.5. ({3+6)/2}
Let's see how to solve this.
First, for a regular set {x₁, ..., xₙ} we define the median as the middle value.
The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.
Here, we have a constant density curve that goes from 3 to 6.
Because it is constant, the median will just be equal to the mean, thus the median is the average between the two extreme values.
Remember that the average between two numbers a and b is given by:(a + b)/2
So we get: m = (6 + 3)/2 = 4.5
So we can conclude that the value of the median is 4.5, so the correct option is the second one, counting from the top.

Answer:
a) We have evidence of the " center stage effect" pair number 3 was selected 34 times almost double the probability of random process
b) probability of ocurrency in random case is 20 %
Step-by-step explanation:
To answer this question we first look at the probability of chossing a pair in case of random selection
P = successful event / total outcomes
P₁ = 1/5
P₁ = 0,2 or P₁ = 20 %
Then if the central pair was selected 34 times from 100 participants ( almost the double ) we have evidence of the center stage effect
P₂ = 34/100 or P₂ = 0,34
