Answer:
If the task is performed in less than or equal to 130.8 seconds, then, the individuals qualify for advanced training.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 150 sec
Standard Deviation, σ = 15 sec
We are given that the distribution of time taken is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.10
P(X < x)
Calculation the value from standard normal z table, we have,
Thus, if the task is performed in less than or equal to 130.8 seconds, then, the individuals qualify for advanced training.
