A population of values has a normal distribution with μ=121.3$\mu =121.3$ and σ=5.8$\sigma =5.8$. You intend to draw a random sample of size n=149$n=149$.

Find the probability that a single randomly selected value is between 119.8 and 121.2.*P*(119.8 < *X* < 121.2)

Find the probability that a sample of size n=149$n=149$ is randomly selected with a mean between 119.8 and 121.2.*P*(119.8 < *M* < 121.2)

Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact *z*-scores or *z*-scores rounded to 3 decimal places are accepted.
