1. Using the information below for the island of Gozo as well as the data for Malta in Table 1, construct and test a series of hypotheses addressing the issue of survival by sex between Malta and Gozo as well as within each island. In simple terms, you will be deconstructing differences between and within a group. From a statistical perspective remember to be explicit in framing your statement of the null hypothesis and your conclusion.
   1. The data for Gozo comes from a hospital where there were 568 patients, 278 died of the plague. When we look at the Gozo patients, 40 % were females and of these 78 died. The data from Malta comes from Table 1.
2. Using your designated data set from Table 1, statistically evaluate whether or not, there was a difference in proportions between blood type O vs non-type O (that is, the combined group of A, B and AB) and survivorship irrespective of sex? State your null hypothesis and conclusions.
3. Using your designated data set from Table 1 look specifically at both blood type as well as sex is there anything unusual about the pattern of association of illness/death due to the plague. Be very specific in your answer by looking at whether biological or social factor(s) might be at play in the table below. Support your explanation with at least two peer reviewed articles.

Table 1. In a hospital in the island of Malta, the following statistics were collected from plague patients during the 1813/14 pandemic.

Plague1
Blood type	Mild symptoms but recovered	Marked symptoms but recovered	Very sick but recovered	Died
A	Men	100	152	141	240
A	Women	30	92	144	240
AB	Men	40	167	319	325
AB	Women	56	167	315	525
B	Men	160	436	440	821
B	Women	120	412	640	1221
O	Men	233	413	958	1550
O	Women	233	813	1359	2550

¹ Plague sickness was evaluated simply in terms of grades of high temperature or fever with the exception of death due to the plague or its complications.
