The height of a certain type of palm tree is normally distributed with mean 45 feet and standard deviation 10 feet. A random sample of fifteen of these palm trees are observed It is of interest to determine the probability that the mean height of these trees is more than 50 feet. Identify the correct formula for solving. O P(X > 50) = P Z > (45-50) O P(X > 50) = P Z> (50-45) V15 O P(X > 50) = P Z > (45-50) V15 O P(X > 50) = P Z > (50-45) V15 O P (X > 50) = P (Z> (50-45) V15 O P(X > 50) = P Z > (50-45) 100 O P(X > 50) = P Z > (50-45) O None of the above Unable to solve
