A population of values has a normal distribution with $\mu = 191.1$ and $\sigma = 94.1$. You intend to draw a random sample of size $n = 195$. Please show your answers as numbers accurate to 4 decimal places. Find the probability that a single randomly selected value is less than 179.6. $P(X < 179.6) =$ Find the probability that a sample of size $n = 195$ is randomly selected with a mean less than 179.6. $P(\bar{x} < 179.6) = $

Step 1
6 using the formula: z = (x - μ) / σ where x is the value, μ is the mean, and σ is the standard deviation. In this case, x = 179.6, μ = 191.1, and σ = 94.1. z = (179.6 - 191.1) / 94.1 Show more…

A population of values has a normal distribution with μ=205.9 and σ=94.8. You intend to draw a random sample of size n=41. Find the probability that a sample of size n=41 is randomly selected with a mean between 182.2 and 191.1. P(182.2 < M < 191.1) = 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=175μ=175 and σ=4.1σ=4.1. You intend to draw a random sample of size n=218n=218. Find the probability that a single randomly selected value is between 175.6 and 175.7. P(175.6 < X < 175.7) = Find the probability that a sample of size n=218n=218 is randomly selected with a mean between 175.6 and 175.7. P(175.6 < M < 175.7)
