Comment on each table/graph as they relate to the assumptions that are being tested

(eg. describe if the image suggests the data is normally distributed and why) and then come to a conclusion about whether the assumption of homogeneity of variance and the assumption of normality have each been met or violated overall.

*each of these 2 assumptions are independent of the other. one can be violated when the other is not violated, vice versa.

Hint* answer should also refer to what the null hypothesis is for each of the numerical tests, whether this null hypothesis is accepted or rejected, and state the p value used to draw this conclusion.
