It is of interest to determine if there is a significant difference in population mean IQ among students from three different schools, at 0.01 level of significance. Following are IQ data from four randomly-selected students from each of the three schools. School H School I School J 100 103 100 100 104 101 102 105 104 104 106 104 What is the null hypothesis?
