Compute the z-score corresponding to each of the values of x below a, x= 45, s= 5, x = 30 b.x-85, -84, -2 d. s 6, x 11, x 20 e. In parts a through d, state whether the z-score locates x within a sample or a population. f. In parts a through d, state whether each value of x lies above or below the mean and by how many standard deviations. a. z 3 (Type an integer or a decimal. Do not round.) b. z= 0.5 (Type an integer or a decimal. Do not round.) c. z = (Type an integer or a decimal. Do not round.) d, z = -1.5 (Type an integer or a decimal. Do not round.) e. For part a, determine whether the z-score locates x within a sample or a population. Choose the correct answer below. The z-score locates x within a sample For part b, determine whether the z-score locates x within a sample or a population. Choose the correct answer below. The z-score locates x within a population. For part c, determine whether the z-score locates x within a sample or a population. Choose the correct answer below. The z-score locates x within a population. For part d, determine whether the z-score locates x within a sample or a population. Choose the correct answer below. The z-score locates x within a sample. f. For part a, state whether the value of x lies above or below the mean and by how many standard deviations. The value of x lies 3 standard deviations above the mean For part b, state whether the value of x lies above or below the mean and by how many standard deviations.

Explanation / Answer

(a) z = (45 - 30)/5 = 3

(b) z = (85 - 84)/2 = 0.5

(c) z = (70 - 70)/5 = 0

(d) z = (11 - 20)/6 = -1.5
