**Question 3: Z-Score Calculations for Given X Values** For a population with a mean (\( \mu \)) of 60 and a standard deviation (\( \sigma_x \)) of 9, find the z-score for each of the following X values: a. \( X = 65 \) b. \( X = 48 \) c. \( X = 75 \) d. \( X = 53 \) **Question 4: X Value from Given Z-Scores** For a population with a mean (\( \mu \)) of 60 and a standard deviation (\( \sigma_x \)) of 9, find the score (X value) that corresponds to each of the following z-scores: a. \( z = -1.00 \) b. \( z = +0.70 \) c. \( z = +1.50 \) d. \( z = +1.75 \)
