4. A researcher is looking at the relative abundance of microbiota in the guts of wild chimpanzees in Cameroon. He randomly selects 25 chimpanzees from the population and analyzes their fecal samples for microbiota abundance. The data is below.
Given alpha = 0.01, perform a hypothesis test to address each of the following questions. Remember to define Ho and Ha, compute the test statistic, define the reject region, estimate the p-value and then state the conclusion.
Is the population mean of microbiota relative abundance different from 0.15?
