Internet and Computer Exercise 1 (From Marketing Research (6th Edition) ,Page 600: Chapter 18, Internet Exercise 1)- Conduct a two-group discriminant analysis on the data given in Tables 18.2 and 18.3 using SPSS (SAS and Minitab not needed). Compare the output and discuss similarities and differences. The comparison is about the similarities and differences in
a) the significance values of the discriminant coefficients,
b) percentage of original grouped cases correctly classified, and
c) percentage of cross-validated grouped cases correctly classified across the three datasets

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
