TRUE OR FALSE

1) if the original x distribution has a relatively small standard deviation, the confidence interval for u will be relatively short. This happens because o decreases, the maximal margin of error E decreases resulting shorter confidence interval.

2) The mean and standard deviation of the standard normal distribution are u= 0 and o= 1
