Ruby v MindTap Week 12 [Revision] X 3. Measures of linear relationship - Covariance and coefficient of correlation Consider a data set consisting of observations for three variables: x, y, and z. Their sample means, variances, and standard deviations are shown in Table 1. Table 1 Sample Mean X = 5 y = 4 Z = 5 Sample Variance S2 = 1 S 2 = 3 S,2 = 13 A-Z Sample Standard Deviation Sx = 1 Sy = 1.732 Sz = 3.606 Table 2 shows the observations for x and y and their corresponding deviations from the sample means. 6 Table 2 Xi yi Xi - X yi - y 6 5 1 1 5 2 O -2 5 -1 1 Type here to search W 02:01 6:06 PM ENG 6/06/2021MindTap Week 12 [Revision] X MindTap - Cengage Learning X + X C ng.cengage.com/staticb/ui/evo/index.html?deploymentld=59911122341710505758528888636&elSBN=9780170389723&id=1121159432...
