Let the predictor variable x be the first variable given The 100 paired measurements yield x = 167 85 cm, y-81 58 kg. r-0 127, P-value-0 208, and y=-108 + 1.10x Find the best predicted value of y (weight) given an adult male who is 177 cm tall. Use a 0.10 significance level The best predicted value of y for an adult male who is 177 cm tall iskg Round to two decimal places as needed.) QUESTION 3 Listed below are the overhead widths (in cm) of seals measured from photographs and the weights of the seals (in kg). The purpose of the study was to determine if weights of seals could be determined from overhead photographs. Is there sufficient evidence to conclude that there is a correlation between overhead widths and the weights of the seals? Use a significance level of α: 0.05 α-0.10 α = 0.06 0.02 a 0.01 Overhead width (cm 7.37.5 9.78.78.3 9.4 Weight (kg) 117 144 199 245 214 200 囲Click the icon to view the critical values of Spearman's rank correlation coefficient.
