"test the claim" b. plz 11/15/2020MyOpenMathA concerned group of citizens wanted to determine whether the proportion of armed robberies in thestate of Texas was different in 2011 than in 2010. Research shows that of the 113,231 violent crimes inTexas in 2010, 7,622 of them were armed robberies. In 2011, 7,439 of the 104,873 violent crimes werein the armed robery category. Test at the 0.05 significance level.Preliminary:a. Is it safe to assume thatn2010 < 5 % of all violent crimes during 2010 andn2011 <5 % of all violent crimes during 2011?NoYesb. Verify np(1 - p) > 10. Round your answer to one decimal place.n2010P (1 -- p) =n2011P (1 – p) =Test the claim;a. Determine the null and alternative hypotheses.Но: р2010 ?На: р2010 ?P2011P2011b. Determine the test statistic. Round to two decimal places.c. Find the p-value. Round to four decimals.p-value =d. Make a decision.Fail to reject the null hypothesis.Reject the null hypothesis.e. Write the conclusion.There is sufficient evidence to support the claim that the proportion of armed robberies isdifferent in 2011 than 2010.There is not sufficient evidence to support the claim that the proportion of armedrobberies is different in 2011 than 2010.

Sy Graphing Calculato... m HBO Max You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. This is because nausea is common for people who have the flu. From past studies you know that about 33% of people who get the flu experience nausea. You collected data on 2371 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 841 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than 33%. *.** ▸ Ezra Mill X HH Chief Be X V H₁: ?
