A new school district superintendent preparing to reallocateresources for physically impaired students wanted to know if theschools in the district differed in the distribution of physicallyimpaired. The superintendent tested samples of 20 students fromeach of the five schools and found 5 physically impaired (and 15unimpaired) students at School 1, 5 physically impaired (and 15unimpaired) at School 2, 6 (and 14) at School 3, 4 (and 16) atSchool 4, and 7 (and 13) at School 5. Using the .05 significancelevel, test whether the distribution of physically impairedstudents is different at different schools. Figure the chi-squarefor this data set yourself (round to two decimal places). What isthe chi-square obtained?
