(True or False) Endogeneity most of the times is caused when important (statistically significant) variables are omitted in the regression model.
Homework Answers
We know that,
Endogeneity in this broad sense can be caused by omitted variables, or unobserved heterogeneity.
Hence,
Given statement is True.

Q23-Statistical power provides the same information as a p-value. True or False? 24. A statistically significant effect (i.e., p < .05) will always be practically meaningful. True or False ? 26. Rejecting the null hypothesis means that the sample outcome is very unlikely to have occurred if H0 is true. True or False ?

True or False 1. If a study finds statistically significant association between exposure and disease, that must mean that every person who is exposed will get the disease. 2. A survey can be reliable but still not close to the true value. 3. Bias is random deviation of results from the truth. 4. Screening for disease is one type of secondary prevention. 5. In order for an infectious disease to occur, there must be a susceptible host.
