Consider the following hypotheses.
Ho: P = 0.13
H₁ p > 0.13
Given that p=0.2, n = 110, and a = 0.01, answer the following questions.

A teacher claims that her students test scores are getting more consistent and now have a lower variation than 2.31, the variation in previous terms. She conducts a hypothesis test. She calculates her test statistic to be y = 15.91 She looks up the critical value for this test and finds it to be y = 11.232. What can she conclude? Hint: Set-up Ho and H, first, draw a sketch and read the answer choices carefully! O A. The test statistic falls in the critical (rejection) region for this test. Therefore, there is sufficient evidence to support her claim. O B. The test statistic falls in the critical (rejection) region for this test. Therefore, there is not sufficient evidence to support her claim, O C. The test statistic does not fall in the critical (rejection) region for this test. Therefore, there is sufficient evidence to support her claim. O D. The test statistic does not fall in the critical (rejection) region for this test. Therefore, there is not sufficient evidence to support her…

Please answer as fast as possible. Please answer all parts of the question and round answers to three decimal points. 2) A random sample of 50 is taken from a population with the following distribution: Y Pr (Y) 0.4 0.6 a) An estimator of the mean of the above distribution is specified as: A = Yı + (2/n), where Yı is the value of the first observation in the sample and n is the sample size (equal to 50). Show whether the bias of this estimator is equal to zero (0). b) Use the same probability distribution as given above, show whether the estimator Ã = Y1 + (2/n) is more efficient than the estimator Y (the sample mean), wheren is equal to 50. c) Show whether the estimator Ã=Y1 + (2/n) is consistent.
