Explanation / Answer

##By using R-software

nausea=c(58,166,193)
> nonausea=c(870,1167,806)
> chisq.test(nausea,nonausea)

Pearson's Chi-squared test

data: nausea and nonausea
X-squared = 6, df = 4, p-value = 0.1991

Chi-squared value is =6

Pvalue is=0.1991

Null Hypothesis: There is no association between seat location and nausea.
