Answer question 1 using data in table 1 below.

Table 1:

Survival Status
Donor’s Sex	Alive	Dead	Total
Female	52	4	56
Male	110	27	137
Total	162	31	193

1. Compute the simple odds ratio of the association of donor’s sex and survival status of the infant. Be sure to answer all four parts to this question (a, b, c, and d), including manual calculation of the chi-square value.

A)Manually calculate a simple odds ratio to test the hypothesis of no association between donor’s sex and the survival status of the infant, without the inclusion of the variable severity using a 2 x 2 table for sex and survival

B)Manually calculate the confidence interval associated with that odds ratio using the appropriate formula

C)Manually compute the Chi Square test statistic for this table

1. Interpret the results. Include an interpretation of the odds ratio, the confidence interval, and the Chi Square test statistic in your response
