A) Find the expected mortality rate for a country with an exposure index of 3?B) Interpret estimated slope of fitted modelC) Provide a null hypothesis, test statistic , p-value and conclusion?D) Dinf the goodness of fit of the model? In 1965, data on the connection between radioactive waste exposure and cancer mortality was published. Thedata was collected from 9 counties that were located near an Atomic Energy Commission facility in Hanford,Washington. The data give the index of exposure and the cancer mortality rate during 1959-1964 for the ninecounties affected. Higher index of exposure values represent higher levels of contamination.CountyExposureMortalityName of countyIndex of exposureCancer mortality per 100,000 man-years"Variable Description:The data is as follows:County Exposure Mortality1 Umatilla2.49147.1Morrow2.57130.13Gilliam3.41129.9Sherman1.25113.5Wasco1.62137.56 HoodRiver3.83162.3Portland11.64207.5Columbia6.41177.99Clatsop8.34210.3S67080 SUMMARY OUTPUTRegression StatisticsMultiple R0.926344821R Square0.858114727Adjusted R Square0.837845402Standard Error14.00992688Observations9.ANOVAdfSSMSSignificance F18309.5559 8309.555942.33560.0003RegressionResidual71373.9464196.2781Total8.9683.5022t StatP-valueCoefficients114.7156Standard Error8.045714.25810.0000Intercept9.23151.41886.50660.0003Exposure

Aspirin III: Decision and Conclusion Regarding the experiment in the data frame Aspirin from the abd package, the researchers wanted to know whether or not taking aspirin affects one's risk of developing cancer. Recall that they defined their parameters as follows: p1 = the proportion of ALL individuals who would develop cancer, if all of them were to take aspirin like the subjects in the Aspirin group did. p2 = the proportion of ALL individuals who would develop cancer, if all of them were to take a placebo, like the subjects in the placebo group did. They ran the code for a two-sided significance test and got the following results: ## ## ## Inferential Procedures for the Difference of Two Proportions p1-p2:## cancer grouped by treatment ## ## ## Descriptive Results:## ## yes n estimated.prop## Aspirin 1438 19934 0.07214## Placebo 1427 19942 0.07156## ## ## Inferential Results:## ## Estimate of p1-p2: 0.0005805 ## SE(p1.hat - p2.hat): 0.002586 ## ##…
I will give a great review/rating! Thank you (:
I know the answer between choice I) and choice II) is: I) But why is it choice I)?
Please let me know if I calculated relative risk correctly. Thank you for your assistance.
