Answer to Question 1

Precision refers to the distance between the lower limit and the upper limit of a confidence interval. The wider the interval the less the precision.

Answer to Question 2

Accuracy is the difference between the observed sample statistic and the actual value of the population parameter being estimated. This may also be referred to as estimation error or sampling error.
