Step 1
In a normal distribution, the 75th percentile is approximately 0.67 standard deviations above the mean. So, if we add 0.67 standard deviations to the mean, we get 50 + 0.67*12 = 58.04. Show more…

True or False: The mean and standard deviation of the distribution of $\bar{x}$ is $\mu_{x}=\mu$ and $\sigma_{x}=\frac{\sigma}{\sqrt{n}},$ respectively, even if the population is not normal.
Sampling Distributions
Distribution of the Sample Mean
If one score is randomly selected from a normal distribution with µ = 100 and σ = 20, the probability of obtaining a score less than X = 95 is p = 0.4013. True False

(T/F) True or False. For an observed value x from any Normal Distribution with known mean and standard deviation, we can always calculate a z-score for this x. True False
