A population of values has a normal distribution with μ=26.2 and σ=85.3. You intend to draw a random sample of size n=226. Find the probability that a single randomly selected value is greater than 15.4. P(X > 15.4) = _______ Find the probability that a sample of size n=226 is randomly selected with a mean greater than 15.4. P(M > 15.4) = ____________ 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 = 225.4 μ = 225.4 and σ = 38.7 σ = 38.7 . You intend to draw a random sample of size n = 13 n = 13 . Find the probability that a single randomly selected value is greater than 252.2. P(X > 252.2) = Find the probability that a sample of size n = 13 n = 13 is randomly selected with a mean greater than 252.2. P(M > 252.2) = 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.

A population of values has a normal distribution with μ=152 and σ=23.7. You intend to draw a random sample of size n=36. Find the probability that a single randomly selected value is between 156 and 157.5. P(156 < X < 157.5) = Find the probability that a sample of size n=36 is randomly selected with a mean between 156 and 157.5. P(156 < M < 157.5) = 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=219.8 and σ=18.6. You intend to draw a random sample of size n=217. Find the probability that a sample of size n=217 is randomly selected with a mean between 216 and 217.7. P(216 < M < 217.7) = 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.
