a. In order to check for the possible relationship between drinking orange juice and protection against the flu virus, research was held during the winter period, which examined a random sample of 600 people who took a daily morning cup of orange juice (test group). In parallel, a control group of 800 randomly chosen people who didn't drink any orange juice during this period was examined as well. It was found that 25% of the people in the test group and 30% of the people in the control group were infected with the flu virus. Based on these results, test, using a 1% significance level, whether there is a relationship between drinking orange juice and protection against the flu virus.
