Student Learning Outcomes . The student will use and derive fundamental concepts from the given information . The student will develop a stronger understanding of calculations behind hypothesis testing. . The student will determine the unknown value by utilizing the acquired knowledge on hypothesis testing. Introduction Let's assume a theoretical scenario. Let's assume that we are asked to determine if a new plant treatment helps a certain species of plant to grow taller. We will only accept success if more than 50% of the treated plant grow taller. In this exercise it is irrelevant what the size of the plant is. 225 plants were treated in this example. The following results for a hypothesis test on proportion is given: Ha:p > 0.5 Ho: 1) : 0.5 We get that the p-value = 0.025 Question Given that x = number of plants that grew taller, and in light of the above information nd: 1. the number (.113) of plants that grew taller and 2. the success rate (pl) of plants that grew taller Project Guidelines Z-Test Statistic p-value measures the area to the right of the test statistic. What is the z-value that has the given p-value? Formula Remember the calculation for the distance of the observed value to the null hypothesis. LII:0 H1 1"] u Z
