M2_JNU';L Prices or diamond jewelry are based on the "4C5" ot diamonds: cut, color, clarity, and carat. A jeweler is trying to estimate the price of diamond earrings based on color, carats, and clarity. The jeweler has collected some data on 22 diamond pieces and the data is shown in Worksheet INDE. The jeweler would like to build a multiple regression model to estimate the price of the pieces based on color, carats, and clarity. a} Prepare a scatter plot showing the relationship between the price and each of the independent variables. bj lfthejeweler wanted to build a regression model using only one independent variable to predict price, which variable should be used? cj Why? dj Hov.r do you use the value of Significance F in the model with only one independent variable? ej If the jeweler wanted to build a regression model using two independent variables to predict price, which variable should be added to the variable selected in the one independent variable model? t'j Why? g] lfthejeweler wanted to build a regression model using three independent variables to predict price, which variable should be added to the variables selected for the two variable model? hj Why? i} Based on your best model, hov.r should thejeweler price a diamond with a color of 2.?5, a clarityr of 3.01], and a weight of 0.85 carats? jj Hov.r do you use the value of Significance F in the multiple regression model? k] Does there appear to be any mu lticollinearity among the independent variables? I} Hov.r can you tell if you have multicollinearity
