Assume the random variable x is normally distributed with mean mu equals 50μ=50 and standard deviation sigma equals 7σ=7. find the indicated probability. upper p left parenthesis x greater than 34 right parenthesisp(x>34)

To get the P(x>34) we proceed as follows:
z-score is given by:
z=(x-mu)/sig
z=(34-50)/7
z=-2.29
Thus:
P(x>34)=1-P(x<34)=1-0.0110=0.989
Answer:  p(X>34)=0.989
