Here are summary statistics on X hits for each of the 64 female archers in the 2008 Olympics:

Archer count 64 Arrow count 4608 Total X's 375 Proportion of X's

0.0814 Mean no. of X's 5.85938 Std Dev in no. of #X's

1. Construct a confidence interval for the proportion of arrows that hit the X circle. Write out your calculation; that is, don’t just report a result from a statistics program. Do the calculation “by hand” (using a calculator or the computer, of course) and show all your work.

2. Interpret the resulting interval.

Archer count 64 Arrow count 4608 Total X's 375 Proportion of X's 0.0814 Mean no. of X's 5.85938 Std Dev in no. of #X's 2.86671
