Answer:
Rational
Step-by-step explanation:
The reason why this number is rational is because this number terminates.
The randomly selected subject is given bone density test which are normally distributed with mean =0 and standard deviation =1. It means bone density test score is standard normal variable.
The probability that a given score is less than 2.23
P(z < 2.23)
Using z score table to find probability below z=2.23
P(z < 2.23) = 0.9871
The probability that a given score is less than 2.23 is 0.9871
You can find the value of p by dividing both sides of the equation by 2. Resulting in 3.5 as the answer
I would go with the first one
