The accompanying data file contains 10 observations with two variables, x₁ and x₂.
a. Based on the entire data set, calculate the sample mean and standard deviation of the two variables. Using the original values, and then the z-score standardized values, compute the Euclidean distance for all possible pairs of the first three observations.
b. Using the original values, and then the z-score standardized values, compute the Manhattan distance for all possible pairs of the first three observations.
