Answer:
286.5 days.
Step-by-step explanation:
This is a normal distribution problem with
Mean = μ = 266 days
Standard deviation = σ = 16 days.
Let the number that corresponds to the top 10% be a.
P(x > a) = 0.1
Let the z-score of a be z'
z' = (x - μ)/σ = (a - 266)/16
Using the normal distribution table, we can obtain the z-score that corresponds to z'
P(x > a) = P(z > z') = 1 - P(z ≤ z') = 0.1
P(z ≤ z') = 1 - 0.1 = 0.9
From the tables, z' = 1.282
P(z ≤ 1.282) = 0.9
And P(z > 1.282) = 0.1
1.282 = (a - 266)/16
16 × 1.282 = a - 266
20.512 = a - 266
a = 286.512 days
Hope this Helps!!!
Scale factors 557 miles? B= around 1000 miles, 1/557
2/1114
C= around 1500
1/557
3/1671
I hope this helps u, I’m not too sure if I’m right
