Suppose we have a bootstrap confidence interval (bCI) for the sample median. The sample size of our data is nn and the number of bootstrap subsamples is BB. For each statement, decide if it is TRUE or FALSE.

1. We make no assumptions about the distribution of the data to perform bootstrapping ? true false
2. We need to know the variance of the population to perform bootstrapping ? true false
3. When nn gets larger, the bCI becomes wider ? true false
4. When BB gets larger, the bCI becomes wider ? true false
5. We need assume the data are normally distributed to perform bootstrapping ? true false
