Question
Report and interpret the P-value for Fisher’s exact test with (i) Ha: θ > 1, and (ii) Ha: θ ̸= 1.
Transcribed Image Text:Table 2.15 contains results of a study comparing radiation therapy with surgery in
treating cancer of the larynx. Some R output follows:
> fisher.test (matrix(c(21,2,15,3),ncol=2,byrow=TRUE), alternative="two.sided")
p-value = 0.6384
> fisher.test (matrix(c (21,2,15,3),ncol=2, byrow=TRUE), alternative= "greater")
p-value - 0.3808
> fisher.test (matrix(c(21,2,15,3),ncol=2, byrow=TRUE), alternative="less")
p-value = 0.8947
