natka813 [3]

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

PART A:
The range, the IQR (inter-quartile range) and the standard deviations are measures which are used to measure the spread of a data set.

A dataset is more consistent relative to another data set when the standard deviation is less than that of the other data set.

From the table, it can be seen that Team C has the least standard deviation.

Therefore, </span><span>If the club wants to award the team that has the most consistent scoring among its team members, team C should be chosen.


PART B
The mean and the median is a measure of center of a data set.
The mean describes the average of a data set.

From the table, it can be seen that Team B has the highest average score.

Therefore, </span><span>If the club wants to award the team with the highest average score, team B should be chosen.</span>
