Exercise 8-10 Algo Need help with multiple choice

Consider the following portion of data that lists the starting salaries (in $1,000) of newly hired employees and their college GPAs:

Employee	Salary	GPA
1	56	3.37
2	58	3.01
3	75	3.84
11	83	3.64

a. Without transforming the values, compute the Euclidean distance for all possible pairs of the first three employees. (Round intermediate calculations to at least 4 decimal places and your final answers to 2 decimal places.)

b-1. Compute the z-score standardized salaries and GPAs for the first three employees. (Round intermediate calculations to at least 4 decimal places and your final answers to 2 decimal places. Negative values should be indicated by a minus sign.)

b-2. Based on the z-score standardized salaries and GPAs, compute the Euclidean distance for all possible pairs of the first three employees. (Round intermediate calculations to at least 4 decimal places and your final answers to 2 decimal places.)

c-1. Based on the z-score standardized salaries and GPAs, compute the Manhattan distance for all possible pairs of the first three employees. (Round intermediate calculations to at least 4 decimal places and your final answers to 2 decimal places.)

c-2. Based on the z-score standardized Manhattan distance values, identify the pair of the first three employees that are most similar. NEED HELP WITH MULTIPLE CHOICE

multiple choice

• Employees 1 and 3 Incorrect

• Employees 1 and 2

• Employees 2 and 3

• Undetermined, because the Manhattan distance values give inconclusive results.
