Problems 11-13 will use the KidsFeet data from the mosaicData package. We will look at the variables length,which is the length of the longer foot (in cm), and width, which is the width of the longer foot (in cm). Letthe explanatory variable be length and response variable be width.11. What is the correlation coefficient of this data?a. -0.3050785b. 0.6410961c. 0.4110041d. 0.0030158e. none of these12. What is the coefficient of determination for this data?a. -0.3050785b. 0.6410961c. 0.4110041d. 0.0030158e. none of these13. What is the least squares regression equation?a. yˆ = 18.5930454 + 0.2479478xb. yˆ = 2.8622761 + 0.2479478xc. yˆ = -31.9892567 + 1.6576239xd. yˆ = -31.9892567 + 1.0626962xe. none of these
