Question

1. Compute the Z scores for the first five values and Compute the Z scores for the next five values.

The data set below is the cost (in cents) per 1-ounce serving for a sample of 13 chocolate chip cookies. Complete parts (a) through (d) below. 52 20 25 23 35 43 10 43 25 45 22 4648 Compute the Z scores for the first five values Z Score Data (X) 52 20 25 23 35 (Round to two decimal places as needed.) Compute the Z scores for the next five values. Z Score Data (X) 43 10 43 25 45 Round to two decimal places as needed.)

2. Compute the Z scores for the last three values.

3.

Answer 1

Solution:-
1) Given that sample : 52,20,25,23,35,43,10,43,25,45,22,46,48

μ = 33.62, σ = 13.37 Z Score = (X-μ)/σ

=> X = 52 Z Score = (52-33.62)/13.37 = 1.37

=> X = 20 Z Score = (20-33.62)/13.37 = -1.02

=> X = 25 Z Score = (25-33.62)/13.37 = -0.64

=> X = 23 Z Score = (23-33.62)/13.37 = -0.79

=> X = 35 Z Score = (35-33.62)/13.37 = 0.10

=> X = 43 Z Score = (43-33.62)/13.37 = 0.70

=> X = 10 Z Score = (10-33.62)/13.37 = -1.77

=> X = 43 Z Score = (43-33.62)/13.37 = 0.70

=> X = 25 Z Score = (25-33.62)/13.37 = -0.64

=> X = 45 Z Score = (45-33.62)/13.37 = 0.85

=> X = 22 Z Score = (22-33.62)/13.37 = -0.87

=> X = 46 Z Score = (46-33.62)/13.37 = 0.3

=> X = 48 Z Score = (48-33.62)/13.37 = 1.08

=> option B.

=> option D.

=> option C.
