A population of values has a normal distribution with μ=196.8 and σ=63.3. You intend to draw a random sample of size n=121. What is the mean of the distribution of sample means? μx̄. What is the standard deviation of the distribution of sample means? σx̄. Round to 4 decimal places.

Step 1
Given that the population mean (μ) is 196.8 and the sample size (n) is 121, the mean of the distribution of sample means (μₓ̄) is equal to the population mean: μₓ̄ = μ = 196.8 Show more…

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.
