Answer:
91.92%
Step-by-step explanation:
Given that:
Mean (μ) = 6.2, standard deviation (σ) = 1.5
Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:
To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3
For x = 8.3, the z score is:
From the probability distribution table:
P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%
