Find the z-score for the value 61, when the mean is 67, and the standard deviation is 5. a) z = -1.20 b) z = -1.40 c) z = 0.84 d) z = -0.84
Added by Jeffery H.
Step 1
Step 1: Calculate the z-score using the formula: \( z = \frac{X - \mu}{\sigma} \), where X is the value (61), μ is the mean (67), and σ is the standard deviation (5). Show more…
