TRUE OR FALSE 1. If A and B are two independent events, then P(AUB) is 2. If the sample correlation coefficient is close to 1 between say X and Y, then we can conclude that X causes Y. 3. In multistage sampling, selection of the sample is done in more than one step 4. A census is a method of gathering information from a subset of the population. 5. A negative probability implies that a certain event is very unlikely to Occur. 6. The chi-square test for independence has degrees of freedom equal to r x c. 8. The mode is the highest value in a set of data.
