The operational flight time, TTT minutes, of a specific survey drone is modeled by a normal distribution such that T∼N(μ,σ2)T \sim \text{N}(\mu, \sigma^2)T∼N(μ,σ2).
It is given that the probability of a flight duration being less than 28.4 minutes is 0.92.
Determine:
P(T>28.4)P(T > 28.4)P(T>28.4)
P(μ<T<28.4)P(\mu < T < 28.4)P(μ<T<28.4)
P(T>μ∣T<28.4)P(T > \mu \mid T < 28.4)P(T>μ∣T<28.4)
