Budget shortfalls in many states during the most recent recession placed a strain on education resources. One area that receives much attention from both parents and administrators is the number of students per teacher. Suppose the U. S. Department of Education would like to compare this ratio in kindergartens for schools in California, Delaware, Nevada, and Georgia. The following data show the number of kindergarten students in randomly selected classrooms in these four states. These data can also be found in the Excel file kindergarten. xlsx.
a. Perform a one way ANOVA using α = 0.05 to determine if the average number of students in kindergarten classes is different in the four states.
b. If warranted, perform a multiple comparison test to determine which pairs are different using α = 0.05.
c. Verify your results with Excel or PHStat.
