1. An educator believes that students choosing to major in mathematics, engineering, chemistry, economics, and philosophy have the same average ACT scores in the population. A random sample of students majoring in mathematics (X1), engineering (X2), chemistry (X3), economics (X4), and philosophy (X5) is taken and each are asked to report their ACT scores. The results are provided below. X1 X2 X3 X4 X5 28 33 28 35 28 21 36 21 18 23 22 30 22 22 26 24 27 19 20 27 32 30 27 27 19 30 26 30 24 23 25 28 22 20 20 29 17 21 26 23 20 20 26 24 26 the Analysis of Variance technique to test the educator's claim at the 0.05 level.
