Given a normal distribution with a mean of 50 and standard deviation of 10, compute the z-score for an individual with xi = 52. Round your answer to three decimal places.
Added by Valerie I.
Step 1
First, we need to calculate the z-score formula: z = (x - μ) / σ where x is the individual's score, μ is the mean, and σ is the standard deviation. Show more…

Assume that X has a normal distribution with the specified mean and standard deviation. mu = 5; sigma = 0.2. Find the 75th percentile, that is the cutoff value of the bottom 75%. Round z-score and your answer to 3 decimal places.

A given distribution has a population mean, μ, of 120 and a population standard deviation, σ, of 10. Compute the raw, x-value associated with a Z-score of -1.65. Round to two decimal places, as needed. Your Answer:
Hoan N.
The mean of a distribution is 10 and the standard deviation is 5. Use the formula below to compute the z-score for the value x = 17. Give your answer as an exact decimal value.
