Question

Answer 1

@campbell_st ur the only 1 left homie

Answer 2

well I'd arrange the score in order, lowest to highest

percentiles are 1/10 ths so 30% = 3/10 * 8 = 2.4

find the score in the 2.4th position

for 90% find the score in the 7.2 position

this is best guess... as I can't ever remember doing percentiles

Answer 3

best guess is 105-100 = 5 * 0.4 = 2 so the 30% percentile is 102

200-176 = 24 24*0.2 = 4.8 90% percentile 180.8
