Question

Go through the ten steps of analysis of variance hypothesis testing to see if you conclude that there is a difference among population means. Let the level of significance be .05 for each test. Use Turkey's HSD procedure to test for significant differences among individual pairs of means (if appropriate). Use the same level of significant value for the F test. Construct a dot plot and side-by-side boxplots of the data.

8.2.7. Thrombocytopaenia is a condition of abnormally low platelets that often occurs during necrotizing
enterocolitis (NEC)-a serious illness in infants that can cause tissue damage to the intestines.
Ragazzi et al. (A-8) investigated differences in the logio of platelet counts in 178 infants with NEC.
Patients were grouped into four categories of NEC status. Group 0 referred to infants with no
gangrene, group 1 referred to subjects in whom gangrene was limited to a single intestinal segment,
group 2 referred to patients with two or more intestinal segments of gangrene, and group 3 referred to
patients with the majority of small and large bowel involved. The following table gives the log10
platelet counts for these subjects.
