A population of values has a normal distribution with $\mu = 32.5$ and $\sigma = 23$. You intend to draw a random sample of size $n = 22$. Find the probability that a single randomly selected value is less than 40.8. $P(X < 40.8) =$ Find the probability that a sample of size $n = 22$ is randomly selected with a mean less than 40.8. $P(M < 40.8) =$ 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.

A population of values has a normal distribution with μ=169.8 and σ=40.6. You intend to draw a random sample of size n=213. Find the probability that a sample of size n=213 is randomly selected with a mean greater than 162.8. P(M > 162.8) = 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. A population of values has a normal distribution with μ=67.9 and σ=77.9. You intend to draw a random sample of size n=235. Find the probability that a sample of size n=235 is randomly selected with a mean between 76.5 and 77.6. P(76.5 < M < 77.6) = 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.
