The probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977
<h3>What is probability?</h3>Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
<h3>How to determine the probability?</h3>The given parameters are:
Mean = 0.8
Variance = 0.0004
Calculate Standard deviation using
σ = √σ²
This gives
σ = √0.0004
Evaluate
σ = 0.02
Calculate the z-score at x = 0.84 using
z = (x - )/σ
This gives
z = (0.84 - 0.8)/0.02
Evaluate
z = 2
The probability is then represented as:
P(x > 0.84) = P(z > 2)
Next, we look up the value of the z table of probabilities
From the z table of probabilities, we have:
P(x > 0.84) = 0.977
Hence, the probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977
