A population of values has a normal distribution with μ=89μ=89 and σ=53.8σ=53.8. A random sample of size n=14n=14 is drawn.



  1. Find the probability that a single randomly selected value is greater than 70.3.Round your answer to four decimal places.


     P(X>70.3)=P(X>70.3)=





  2. Find the probability that a sample of size n=14n=14 is randomly selected with a mean greater than 70.3.Round your answer to four decimal places.

    P(M>70.3)=
