A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)
Answer: .69
Step-by-step explanation:
Answer on khan
We can write the value in the range P(64 < {x} < 76) as 0.68.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.
It is given that -
μ = 70
σ = 6
For the range of {x}, we can write -
(μ - σ) < {x} < (μ + σ)
64 < {x} < 76
We can write the range of {z} value as -
(64 - 70)/6 < {z} < (64 + 70)/6
- 1 < {z} < + 1
Now -
P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68
Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.

0. The weight of an object on the Moon is about 16.5% of its weight on Earth. The weight of an astronaut on the Moon is 24.75 pounds. How much does the astronaut weigh on Earth?
Answer: 150 pounds
Step-by-step explanation:
Let the the astronaut weight on Earth be represented by x.
Based on the information given in the question, thus can be formed into an equation as:
16.5% of x = 24.75
16.5% × x = 24.75
16.5/100 × x = 24.75
0.165x = 24.75
x = 24.75/0.165
x = 150 pounds
The astronaut weigh 150 pounds on Earth.
