Problem Set 8 1) In which special circumstances can cross-sectional studies be used to make statements regarding causal inference (i.e., whether exposure causes outcome)? - When exposure variables are unaltered over time, such as eye color or blood group, results from cross-sectional studies may be used to provide evidence towards causal inference. - Cross-sectional studies can be used when we need to discern the temporal relationship between exposure and disease. - When the risk factors under study can change over time and as a consequence of the disease process, cross-sectional data can confirm the presence of an association. - Cross-sectional studies can never be used to test hypotheses

Before determining the amount of \( \mathrm{Na}_{2} \mathrm{CO}_{3} \) in a sample, you decide to check your procedure by analyzing a standard sample that is \( 98.76 \% \mathrm{w} / \mathrm{w} \mathrm{Na}_{2} \mathrm{CO}_{3} \). Five replicate determinations of the \%w/w \( \mathrm{Na}_{2} \mathrm{CO}_{3} \) in the standard gave the following results: wt/wt \( \% \mathrm{Na}_{2} \mathrm{CO}_{3}: 98.71,98.59,98.62,98.44,98.58 \) Using \( \alpha=0.05 \), is there any evidence that the analysis is giving inaccurate results?
