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: H.: p>0.5. H: p=0.5. We get that the p-value = 0.025 Given that x number of plants that grew taller, and in light of the above information find: 1. the number (x)(x) of plants that grew taller and 2. the success rate (p» (p) of plants that grew taller Question p-value measures the area to the right of the test statistic. What is the z-value that has the given p-value? I

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e. g. 98.7654). x f(x) 0 1 2 3
