A population of values has a normal distribution with μ=151.5μ and σ=75.8. You intend to draw a random sample of size n=92. Find the probability that a single randomly selected value is between 138.9 and 174.4. P(138.9 < X < 174.4) =  Find the probability that a sample of size n=92 is randomly selected with a mean between 138.9 and 174.4. P(138.9 < ¯x < 174.4) =  Enter your answers as numbers accurate to 4 decimal places. Answers should be obtained using z-scores correct to two decimal places.
