Answer:
Option B - 65%
Step-by-step explanation:
Given : Suppose the x-axis of a density graph represents someone's height in inches. If the area under the density curve from 60 inches to 70 inches is 0.65.
To find : What is the probability of someone's height being anywhere from 60 inches to 70 inches?
Solution :
The probability percentage of a curve is defined as the area under the density curve as
P=\int\limits^a_b {e^{f(x)}} \, dx =A
The area under the density curve from 60 inches to 70 inches is 0.65.
So,The probability is equal to the area = 0.65
Therefore, The probability of someone's height being anywhere from 60 inches to 70 inches is 65%.
Hence, Option B is correct.
