In the most simplistic terms: How is the rejection region defined, and how is that related to the p values?
Homework Answers
Rejection region is the area which indicates the area beyond
critical values.
A null hypothesis is rejected if test statistic lies in the
rejection region.
p-value is the probability of getting the test statistic if the
null hypothesis is true.
Hence p-value is also indicates the area.
if the p-value area is less than the rejection region area, we
reject the null hypothesis

Hint: Critical region is a synonym for rejection region. In a fair “Pick 3” game, the first digit drawn should be a zero with probability 0.1 because there are ten equally likely outcomes. A lottery player suspects that the game is unfair. To test his theory, he records the numbers drawn over two years which constitute 582 plays. a) (4 points) Write down the critical region for testing whether or not the probability of drawing a 0 first is actually...

How do you find rejection regions? Here's the question: Two different companies have applied to provide cable television service in a certain region. Let p denote the proportion of all potential subscribers who favor the first company over the second. Consider testing H_0: p =0.5 vs. H_a: p != 0.5 based on a random sample of 25. Let the test statistic X be the number in the sample who favor the first company and x represent the observed value of...

For the following cases, you may use either the P-value approach or the rejection region approach to present a full hypothesis test, including: Identifying the claim and H0 and Ha, Finding the appropriate standardized test statistic, Finding the P-value or the rejection region, Deciding whether to reject or fail to reject the null hypothesis, and Interpreting the decision in the context of the original claim. A city planner claims that the mean speed of westbound traffic along a road segment...
