Mr. P.H. Official is reviewing data in order to determine the source(s) of a foodborne illness in his jurisdiction. Based on the following results, which is the likely source? (Results are odds ratios.)
| a. 1.5 (95% CI = +/- 0.8 ) p<=0.05 |
| b. 0.5 (98% CI = +/- 0.2) p<=0.05 |
| c. 2.5 (95% CI = +/- 1.0 ) p<=0.05 |
| d. 3.0 (98% CI = +/- 2.2 ) p<=0.05 |
Option C is correct as per considering the odd ratios
At the 95% class interval and the 0.05 level of the significance

Exhibit L.1 reports the multivariate odds ratios comparing each category to women who never had an induced abortion and had at least one pregnancy. Researchers were able to interview 845 out of 1,011 (83.5 percent) of the eligible cases and 961 out of 1,239 (78 per- cent) of the eligible controls. Of the cases, only 689 (81.5 percent) had complete information on abortion history, compared to 781 (81.3 per- cent) of the eligible controls. Abortion History Cases Controls Crude OR2...

The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
