Question 16While watching a rousing debate on cable television between two presidential candidates, your TVscreen suddenly goes blank and silent. In the space below, describe three hypotheses designed toexplain what has gone wrong, and a test for each hypothesis. Each of your three hypotheses mustbe entirely distinct from the other two, and you must describe the tests for each hypothesis thoroughly,carefully indicating how the various possible results of each test would bear upon the hypothesis inquestion (e.g., strongly confirm it, weakly refute it, etc.). [Feel free to be creative and have a little funwith some of your hypotheses.]Edit ViewInsertFormatToolsTable12pt vParagraph v B I U Av &v T?v...

Question 15: In a recent Super Bowl, a TV network predicted that 90 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 55 people who saw the commercials and found that 48 of them said they would watch one of the television shows.Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.9H0:p=0.9Ha:p>0.9Ha:p>0.9Calculate the test statistic, rounded to 3 decimal places z=
Question 16 In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 120 tests are conducted using a significance level of 5%, approximately how many of the tests will incorrectly find significance?Enter your answer in accordance to the question statement of the tests will find significance.

Answer A, B1, and B2: A. The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population. B. Researchers interested in lead exposure due to car exhaust sampled the blood of 52 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 124.32 µg/l and a SD of 37.74 µg/l; a previous study of individuals from a nearby suburb, with no history of exposure, found an average blood level…
Past records from a local hospital stated that the proportion of full-term babies born in the hospital who weigh less than seven pounds is 43%. Suppose that we have strong reason to believe the proportion is greater than 43%, and we wish to carry out a hypothesis test. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0: H1:
Question #: 16 In hypothesis testing, the null hypothesis is a statement assumed to be A) true unless we have strong evidence that it is false. B) false unless we have strong evidence that it is true. C) true regardless of the nature of our evidence. D) false regardless of the nature of our evidence.

A new insecticide is advertised to kill more than 95% roaches upon contact. In a laboratory test, the insecticide was applied to 400 roaches and 384 died immediately after contact. Is this sufficient evidence to support the advertised claim? Use α=0.05. (a) Alternative hypothesis for the problem above is
Question 23: The National Institute of Mental Health published an article stating that in any one-year period, approximately 9% of American adults suffer from depression or a depressive illness. Suppose that in a survey of 2000 people in a certain city, 10% of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that city suffering from depression or a depressive illness is more than the 9% in the general adult American population. Test the relevant hypotheses using a 10% level of significance. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) H0: H1: Based on the hypotheses, find the following: Test Statistic = p-value = Based on the above we choose to The correct summary would be: that the true proportion of people in that city suffering from depression or a…
