For both tests, use α = 0.05.It has been observed that Crenshaw’s students don’t seem to do in well in math. To investigate that, for the 19 students who had Crenshaw in 5th grade, determine whether or not their math scores decreased from 4th to 5th Use α = 0.05. Do the same for the 17 students who had Davis in 5th grade. What can you conclude from these tests?On the other hand, Crenshaw’s students seem to excel in language arts. To investigate that, for the 19 students who had Crenshaw in 5th grade, determine whether or not their language arts scores increased from 4th to 5th Use α = 0.05. Do the same for the 17 students who had Davis in 5th grade. What can you conclude from these tests?On the basis of questions 4 through 6, what would you, as an administrator, recommend regarding Crenshaw and Davis?
