For a distribution with a standard deviation of σ = 20, describe the location of each of the following z-scores in terms of its position relative to the mean. For example, z = 11.00 is a location that is 20 points above the mean.
Answer to relevant QuestionsFor a population with μ = 80 and σ = 10, a. Find the z-score for each of the following X values. b. Find the score (X value) that corresponds to each of the following z-scores. (Again, you should not need a formula or any ...A sample has a mean of M = 25 and a standard deviation of σ = 5. For this sample, find the X value corresponding to each of the following z-scores. The distribution of SAT scores is normal with μ = 500 and σ = 100. a. What SAT score, X value, separates the top 15% of the distribution from the rest? b. What SAT score, X value, separates the top 10% of the distribution ...What are the two requirements that must be satisfied for a random sample? A normal distribution has a mean of µ = 60 and a standard deviation of σ = 18. For each of the following samples, compute the z-score for the sample mean and determine whether the sample mean is a typical, representative ...
