Answer:
6.0520
Step-by-step explanation:
Given that:
Mean = 5.85
Standard deviation = 0.24
Let N denote the 80th percentile.
P(X < N) = 0.8
Using the Excel formula: = NORM.INV(0.8,5.85,0.24)
The 80th percentile for the diameters of mandarin oranges:
= 6.0520 (to 4 decimal place)
Seems like a proportions problem
In 15, you have 3 boxes and your partner has 1. Total 4 boxes. Each represents 12/4=3 hours. So you have 3 boxes = 3*3=9 hours and your friend has 3 hours.
Same method in 16. You have 4 and your friend has 8
