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.
-A company claims that the proportion of defectives among its new DVD players is only $0.01 ( 1 \% )$ . A consumer group believes that the proportion of defectives is higher than this. The consumer group picks a random sample of 200 of the DVD players and finds the proportion of defectives in the sample to be $0.022$ . Assuming that the proportion of defectives for all the company's DVD players is $p = 0.01$ , the probability of selecting a sample in which the proportion of defectives is $0.022$ or more is $0.044$ .
