The result of a hypothesis is described in terms of the probability of obtaining a particular sample. Use the given context to formulate the null and alternative hypotheses. Discuss whether the sample provides evidence for rejecting the null hypothesis.The mayor of a city claims that racial profiling is not a problem in his city. A civil rights group disagrees. The proportion of Caucasians who have been stopped while driving, without good reason, at least once in the past year is 0.19 (19%). In a random sample of 340 African Americans , the proportion who have been stopped is 0.37 (37%). Assuming that the proportion of all African Americans in the city that have been stopped is 0.19, the probability of selecting a sample in which the proportion who have been stopped is 0.37 or
more is less than 0.001. What will be an ideal response?
