Four laboratories are being used to perform chemical analysis. Samples of the same material are sent to the laboratories for analysis as part of the study to determine whether or not they give, on the average, the same results. The analytical results for the 4 laboratories are as follows: Laboratory A B C D 59.7 62.7 55.9 60.7 61.4 64.5 56.1 60.3 60.9 63.1 57.3 63.8 59.1 59.2 55.2 61.4 58.2 70.3 60.1 62.3 Which of the following is the correct ANOVA table? a Source of variation Sum of squares Degrees of freedom Mean square Computed f Column means 85.83 3 28.642 13.37 Error 34.28 16 2.1425 Total 120.11 19 Source of variation Sum of squares Degrees oi freedom Mean square Computed f Column means 85.93 3 28.642 13.33 Error 34.38 16 2.149 Total 120.31 19 Source of variation Sum of squares Degrees oi freedom Mean square Computed f Column means 85.13 3 28.3767 13.2046 Error 34.38 16 2.149 Total 119.51 19 d Source of variation Sum of squares Degrees of freedom Mean square Computed f Column means 132.95 3 44.32 7.461 Error 95.03 16 5.95 Total 227.98 19Suppose that we want to build a model that predicts the group membership of a hurricane, either tropical (0) or non-tropical (1) based on the latitude of formation of the hurricane. The response variable is the binary variable Type . new (type of hurricane) and the predictor variable is FirstLat (First Latitude). Using R. we build a model by applying the glim () function. For the logistic regression model, we specify family = "binomial". The data is available at https://userpage.fu-berlin.de/soga/200/2010 data sets hurricanes xiox .
