Side-by-Side Use a significance test to compare the proportions Calculate the test statistic z Give your answers to two decimal places In 1898 the United States and Spain fought a war over the U.S. intervention in the Cuban War of Independence. At that time, the U.S. military was concerned about the nutrition of its recruits. Many did not have a sufficient number of teeth to chew the food provided to soldiers. As a result, it was likely that they would be undernourished and unable to fulfill their duties as soldiers. The requirements at that time specified that a recruit must have "at least four sound double teeth, one above and one below on each side of the mouth, and so opposed" so that they could chew food. Of the 58,952 recruits who were under the age of 20,68 were rejected for this reason. For the 43,786 recruits who were 40 or over, 3801 State the conclusion for the test. 12 were rejected. We fail to reject the null hypothesis. There is evidence that there is a difference between age- groups in the rejeciton rate during the Spanish- American War due to bad teeth.
