Suppose a set of data has mean $\mu = 12$ and standard deviation $\sigma = 1.7$. (Give answers accurate to three decimal places.) a. What is the z-score for the data value $x = 11$? $z = $ b. What is the z-score for the data value $x = 15$? $z = $ c. What data value corresponds to the z-score: $z = 1.6$? $x = $ d. What data value corresponds to the z-score: $z = -1.4$? $x = $

Step 1
a. For x = 11: z = (11 - 12) / 1.7 z = -0.588 b. For x = 15: z = (15 - 12) / 1.7 z = 1.765 Show more…
