1. The Brazilian Forest Service (Servico Florestal Brasileiro, SFB) is faced with the need to restrict vehicles and visitors to their national forests which are being threatened. According to the latest survey results, it was estimated that 86% of Brazilians from one state called Amazonas support such restrictions and 54% of Brazilians from another state called Bahia support the restrictions. The SFB conducts a random sample of 300 Brazilians from Amazonas and another random sample of 250 Brazilians from Bahia. A. Find the mean and standard deviation of the sampling distribution of p, - P2. Interpret the mean and standard deviation. B. Describe the shape of the sampling distribution of p, - P2. Justify your answer. C. What is P(Pi - P2) >0 ? D. Interpret your answer to part C in context.
