The Result of a Hypothesis Is Described in Terms of the Probability

Essay

The result of a hypothesis is described in terms of the probability of obtaining a particular sample. Use the given contextto formulate the null and alternative hypotheses. Discuss whether the sample provides evidence for rejecting the nullhypothesis.
-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 $0.001$ .
