A manufacturing company produces water filters for home refrigerators. The process has typically produced about 4% defective liters. A new design experiment has led to change the seal to reduce defects. With the process running using the new seal, a random sample of 300 liters yielded 7 defects. Conduct a hypothesis test at the 10% significance level. 1. Set up the null and alternative hypotheses. 2. Compute the test statistic. 3. State the p-value for the test. Also, state the decision and conclusion of the test in context
