For the following two questions, consider the following relative risks (and their confidence intervals), where our exposure is burns and the outcome is skin infection.
Unadjusted: 1.74 (0.97, 2.95)
Age Adjusted: 1.77 (0.98, 2.98)
Gender Adjusted: 2.60 (1.36, 4.12)
Race Adjusted: 2.23 (1.12, 3.32)
Which measures show a statistically significant association between burns and skin infection? Select all that apply.
here as Gender Adjusted and Race Adjusted: measure does not contain 1 in their confidence intervla
therefore they are statistically significant
optionC and D are correct
For the following two questions, consider the following relative risks (and their confidence intervals), where our...

1. Two manufacturing processes are being compared to try to reduce the number of defective products made. During 8 shifts for each process, the following results were observed: Line A Line B n 181 | 187 Based on a 5% significance level, did line B have a larger average than line A? *Use the tables I gave you in the handouts for the critical values *Use the appropriate test statistic value, NOT the p-value method *Use and show the 5...
