You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patientswith the flu and say that nausea is a side effect if people become nauseous. This is because nausea iscommon for people who have the flu. From past studies you know that about 32% of people who get the fluexperience nausea. You collected data on 2494 patients who were taking Tamiflu to relieve symtoms of theflu, and found that 870 experienced nausea. Use a 0.01 significance level to test the claim that thepercentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than32%.a) Identify the null and alternative hypotheses?Ho: ? vHa: ? vb) What type of hypothesis test should you conduct (left-, right-, or two-tailed)?O left-tailedO right-tailedO two-tailedc) Identify the appropriate significance level.Submit Question3.

In each part, we have given the significance level and the P-value for a hypothesis test. For each case determine if the null hypothesis should be rejected. Write "reject" or "do not reject" (without quotations - if you like use copy and paste to avoid typos). (a) α= 0.01, P = 0.06 answer: (b) a = 0.06, P = 0.001 answer: (c) a = 0.07, P = 0.06 answer:

Does more education lower a person’s level of prejudice? The number of years of education and the score on a prejudice test for ten people is given in the following table. Higher scores on the test indicate more prejudice. Years of Education: 12, 15, 14, 13, 18, 10, 16, 12, 10, 4 Score of Prejudice Test: 1, 6, 2, 3, 2, 4, 1, 5, 5, 10 Conduct a hypothesis test to determine if there is a significant linear correlation between the two variables. If there is a significant linear correlation between the variables, determine the regression equation. There is a significant correlation between the variables and the regression equation is y' = 10.5 - 0.532x There is a significant correlation between the variables and the regression equation is y' = - 0.532 + 10.5x There is not a significant correlation between the variables, so the regression equation should not be determined. There is a significant correlation between the variables and the regression equation is y' = 16.509 - 1.054x
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? E Click the icon to view the table. Determine the null and alternative hypotheses. O A.
