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
Hello!
Let's begin by multiplying all 3 terms by 4, to remove the fraction:
2(r-3) - 8(4) = 50(4)
Then 2r - 6 - 32 = 200. Consolidating the constants on the right side, we get:
2r = 162. Solving for r, we divide both sides by 2, obtaining r = 81 (answer)
