Answer:
Step-by-step explanation:
Normally Z scores in a std normal distribution curve lie between -3 and 3 comprising more than 99% of total area.
Any entry outside (-3,3) can be considered as an extreme observation.
Here we have hence a) -4.3 is the most extreme observation.
-------------------------
Given that 84 separates the lowest 75% of the scores from the highest 25% of the scores,
This means 84 is the 75th percentile and similarly 65 is the 25th percentile.
Thus we have 84 has the percentile rank of 75
Option C
Answer:
After 6 rounds one team will win.
Step-by-step explanation:
This is an example of geometric progression,
Let p(n) represents the number of participants remaining after n rounds of play.
First term = 64

We have

Number of teams remaining after n rounds of play, p(n) = 2⁶⁻ⁿ
Here we need to find for what n p(n)=1

After 6 rounds one team will win.
