For a population with a mean of μ= 40 and a standard deviation of σ= 6, find the z-score corresponding to each of the following samples: a. M = 43 for a sample of n =4 b. M = 43 for a sample of n = 16
Added by Brenda O.
Step 1
The standard error (SE) is calculated as: SE = σ / √n For sample a (n = 4): SE_a = 6 / √4 = 6 / 2 = 3 For sample b (n = 16): SE_b = 6 / √16 = 6 / 4 = 1.5 Now, we can calculate the z-scores for each sample. The z-score is calculated as: Show more…

For a population with a mean of µ=60 and standard deviation of σ=24, find the z-score corresponding to each of the following samples: a. M=63 for a sample of n=16 scores b. M=63 for a sample of n=36 scores c. M=63 for a sample of n=64 scores

A sample of n = 64 scores has a mean of M = 68. If the population mean is μ = 60, find the z-score for these samples with the following standard deviations: a. σ = 16 _______ b. σ = 32 _______ c. σ = 48 _______

In a population of scores, X = 44 corresponds to z = +0.50 and X = 50 corresponds to z = +2.00. What are the values for the population mean and standard deviation? a) μ = 42 and σ = 4 b) μ = 43 and σ = 2 c) μ = 40 and σ = 8 d) μ = 41 and σ = 6
