A recent study was conducted where 59 men, and 59 women, were observed washing their hands. Of the 59 men, 19 were observed as not washing their hands. Of the 59 women, 8 were observed not washing their hands. The claim is that women are 50% more likely to wash their hands than men. Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.
